- CDPD-53176: Partition Specification data for Iceberg Table is not sent to Atlas in Hook context
- When a Iceberg table is created with partition spec, partition
specification data is not sent to Atlas in Hook context. The partition specification data
is stored differently for Hive than for Spark and Impala.
For example, for Spark and Impala, the partition data is present in Table parameters.default-partition-spec but for Hive partition data is stored in Partition Transform Information and not Table parameters.default-partition-spec. In case of Hive, Atlas is not getting Partition Transform Information or Table parameters.default-partition-spec from Hook context.
- CDPD-59413: Plugin is not supported with older Atlas server versions for Iceberg tables
-
Copy the model file 1130-iceberg_table_model.json to the directory:
/opt/cloudera/parcels/CDH/lib/atlas/models/1000-Hadoop
.Proceed to restart the Atlas Service using Cloudera Manager.
- CDPD-56590: Create table "like" from Iceberg table creates a hive_table instead of iceberg_table
- By default, for tables created using the "like" command, lineage is not generated in Atlas. The destination like table should be of the same type as source table. Instead an iceberg_table for source and hive_table for destination are getting created.
- CDPD-56085: [Impala Iceberg] LOAD DATA INPATH to Iceberg_table creates a temporary hive_table with name <iceberg_table_name>_tmp* and then marks it as DELETED in Atlas
- Running a query like "LOAD DATA INPATH to iceberg_table", creates a temporary hive_table with name <iceberg_table_name>_tmp* and then marks it as DELETED in Atlas. So in Atlas, a deleted entity is created corresponding to the temporary table "<iceberg_table_name>_tmp*".
- CDPD-67112: Import transforms do not work as expected when replacing a string which already has ":"
- None
- CDPD-67022: Export/Import: When a user with export/import permissions does not have the permission to create/read/write/update entity, the import operation fails with 403 error
- The entity permission for
__AtlasAuditEntry
has to be present.
- CDPD-67020: When a user has export/import permissions but no other permission on entity (read/write/update), export operation throws an error, import operation fails
- The entity permission for
AtlasServer
and__ExportImportAuditEntry
has to be present.
- CDPD-65806: After upgrading from Cloudera Runtime 7.2.17 to 7.2.18, not all Iceberg table relationships are visible in the entity details page
- None
- OPSAPS-68461: Update GC and JVM options for Atlas service for supporting JDK17 in main Atlas CSD
- Existing ATLAS OPTS does not work for JDK17. You must manually update ATLAS_OPTS.
- DOCS-19084: Atlas Rolling Upgrade related to Zero Downtime Upgrade (ZDU)
- Upgrade process comprises of upgrading Cloudera Manager + Runtime upgrade + Operating System upgrade. Though Atlas cannot comply with a full ZDU process, there is no data loss observed through the entire upgrade process. Post upgrade, all the created entities before and during the upgrade process are available without any changes or modifications.
- CDPD-62973: Change in audits behavior in Cloudera Runtime 7.2.18 deployment.
- When the value of differential audits is set as true, the audit information is not segregated based on the user which is firing the query. The HMS service user information includes details of the service user. When differential audit is enabled, only the difference between the two subsequent audits is logged, but in this case, there is no change in the data which is retrieved from HS2 and HMS, which does not create the audit. The user information is audited fine when differential audit is disabled
- DOCS-19610: After upgrading from Cloudera Runtime 7.2.17 to 7.2.18, not all Iceberg table relationships are visible in the entity details page
- The following entities are affected:
- relationshipAttributes
- hive partition_spec
- database details missing
- ddl_queries
- CDPD-63397: During Data Lake upgrade, Atlas authorization is denied
-
When rolling upgrade is performed, there might be a scenario where Ranger Admin could be undergoing upgrade by itself and hence the policy download could be affected.
During this period, access might be denied for certain Atlas entities. This issue is resolved once Ranger Admin is up and the policies are downloaded.
- CDPD-55301: The ddlQueries and ALTERTABLE_* lineage are missing for Spark tables created using spark3-shell
- The ddlQueries and outputFromProcesses (lineage) is missing for the alter queries.
- CDPD-40346: The ddlQueries and ALTERTABLE_ADDCOLS lineage missing for Impala tables
- The
ALTERTABLE_ADDCOLS
lineage has some issue when an Impala table is altered and the corresponding lineage is not created. - CDPD-55671: When one Atlas server host is not reachable (stopped), the GET request does multiple failover for approximately 4 minutes and takes around 2 minutes for every failover and finally the request fails.
- None
- CDPD-55122: Any user with ssh access can view the downloaded results
- None
- CDPD-57549: Rolling upgrade / ZDU: Atlas throws 503 when Zookeeper goes through upgrade
- When Zookeeper goes through Rolling upgrade, Atlas REST calls throws 503 error. Entities created using Atlas Kafka hook are created in Atlas and no data loss is expected.
- CDPD-46606: Performing Hive queries renders a notification for update data in the Hive table
- None
- CDPD-24089: Atlas creates HDFS path entities for GCP path and the qualified name of those entities does not have a cluster name appended.
- None
- CDPD-45642: When REST Notification server is down, messages from hooks are lost
- None
- CDPD-46940: REST notification need to be disabled when running import scripts
- None
- CDPD-22082: ADLS Gen2 metadata extraction: If the queue is not cleared before performing Incremental extraction, messages are lost.
- After successfully running Bulk extraction, you must clear the queue before running Incremental extraction.
- CDPD-19996: Atlas AWS S3 metadata extractor fails when High Availability is configured for IDBroker
- If you have HA configured for IDBroker, make sure your cluster has only one IDBroker address in core-site.xml. If your cluster has two IDBroker addresses in core-site.xml, remove one of them, and the extractor must be able to retrieve the token from IDBroker.
- ATLAS-3921: Currently there is no migration path from AWS S3 version 1 to AWS S3 version 2
- None
- CDPD-11941: Table creation events missed when multiple tables are created in the same Hive command
- When multiple Hive tables are created in the same database in a single command, the Atlas audit log for the database may not capture all the table creation events. When there is a delay between creation commands, audits are created as expected.
- CDPD-11940: Database audit record misses table delete
- When a hive_table entity is created, the Atlas audit list for the parent database includes an update audit. However, at this time, the database does not show an audit when the table is deleted.
- CDPD-11692: Navigator table creation time not converted to Atlas
- In converting content from Navigator to Atlas, the create time for Hive tables is not moved to Atlas.
- CDPD-11338: Cluster names with upper case letters may appear in lower case in some process names
- Atlas records the cluster name as lower case in
qualifiedNames
for some process names. The result is that the cluster name may appear in lower case for some processes (insert overwrite table) while it appears in upper case for other queries (ctas) performed on the same cluster. - CDPD-10576: Deleted Business Metadata attributes appear in Search Suggestions
- Atlas search suggestions continue to show Business Metadata attributes even if the attributes have been deleted.
- CDPD-10574: Suggestion order doesn't match search weights
- At this time, the order of search suggestions does not honor the search weight for attributes.
- CDPD-9095: Duplicate audits for renaming Hive tables
- Renaming a Hive table results in duplicate ENTITY_UPDATE events in the corresponding Atlas entity audits, both for the table and for its columns.
- CDPD-7982: HBase bridge stops at HBase table with deleted column family
- Bridge importing metadata from HBase fails when it encounters an
HBase table for which a column family was previously dropped. The error indicates:
Metadata service API org.apache.atlas.AtlasClientV2$API_V2@58112bc4 failed with status 404 (Not Found) Response Body ({""errorCode"":""ATLAS-404-00-007"",""errorMessage"":""Invalid instance creation/updation parameters passed : hbase_column_family.table: mandatory attribute value missing in type hbase_column_family""})
- CDPD-7781: TLS certificates not validated on Firefox
- Atlas is not checking for valid TLS certificates when the UI is opened in FireFox browsers.
- CDPD-6675: Irregular qualifiedName format for Azure storage
- The qualifiedName for
hdfs_path
entities created from Azure blog locations (ABFS) doesn't have the clusterName appended to it as dohdfs_path
entities in other location types. - CDPD-4762: Spark metadata order may affect lineage
- Atlas may record unexpected lineage relationships when metadata collection from the Spark Atlas Connector occurs out of sequence from metadata collection from HMS. For example, if an ALTER TABLE operation in Spark changing a table name and is reported to Atlas before HMS has processed the change, Atlas may not show the correct lineage relationships to the altered table.
- CDPD-4545: Searches for Qualified Names with "@" doesn't fetch the correct results
- When searching Atlas qualifiedName values that include an "at" character (@), Atlas does not return the expected results or generate appropriate search suggestions.
- CDPD-3208: Table alias values are not found in search
- When table names are changed, Atlas keeps the old name of the table in a list of aliases. These values are not included in the search index in this release, so after a table name is changed, searching on the old table name will not return the entity for the table.
- CDPD-3160: Hive lineage missing for INSERT OVERWRITE queries
- Lineage is not generated for Hive INSERT OVERWRITE queries on partitioned tables. Lineage is generated as expected for CTAS queries from partitioned tables.
- CDPD-3125: Logging out of Atlas does not manage the external authentication
- At this time, Atlas does not communicate a log-out event with the external authentication management, Apache Knox. When you log out of Atlas, you can still open the instance of Atlas from the same web browser without re-authentication.
- CDPD-1892: Ranking of top results in free-text search not intuitive
- The Free-text search feature ranks results based on which attributes match the search criteria. The attribute ranking is evolving and therefore the choice of top results may not be intuitive in this release.
- CDPD-1884: Free text search in Atlas is case sensitive
- The free text search bar in the top of the screen allows you to search across entity types and through all text attributes for all entities. The search shows the top 5 results that match the search terms at any place in the text (*term* logic). It also shows suggestions that match the search terms that begin with the term (term* logic). However, in this release, the search results are case-sensitive.
- CDPD-1823: Queries with ? wildcard return unexpected results
- DSL queries in Advanced Search return incorrect results when the query text includes a question mark (?) wildcard character. This problem occurs in environments where trusted proxy for Knox is enabled, which is always the case for CDP.
- CDPD-1664: Guest users are redirected incorrectly
- Authenticated users logging in to Atlas are redirected to the CDP Knox-based login page. However, if a guest user (without Atlas privileges) attempts to log in to Atlas, the user is redirected instead to the Atlas login page.
- CDPD-922: IsUnique relationship attribute not honored
- The Atlas model includes the ability to ensure that an attribute can be set to a specific value in only one relationship entity across the cluster metadata. For example, if you wanted to add metadata tags to relationships that you wanted to make sure were unique in the system, you could design the relationship attribute with the property "IsUnique" equal true. However, in this release, the IsUnique attribute is not enforced.
- CDPD-67450: Table name renaming operation is not updating or creating iceberg_table entity
- Renaming an Iceberg Table does not update the corresponding Atlas entity.
- CDPD-65619: Newly created Iceberg tables do not show up under hive_db entity
- Currently, on single
typename
is shown under the Tables tab. Both Iceberg and Hive tables cannot be shown when they are created in the same hive_db entity. - CDPD-69910: NPE while deleting BusinessMetadata
- If business metadata is created without adding any applicable types, a NullPointerException is produced when we try to delete that business metadata.
