OPSAPS-58664: Hive on Tez LDAP configurations are not pushed to hive-site.xml by Cloudera Manager

After setting up LDAP properties in the Hive on Tez service, the settings are not pushed into hive-site.xml for Hive on Tez service even after a restart. The issue is due to HiveOnTezServiceHandler re-using definitions from HiveConfigFileDefinitions. The definitions are not including any roletypes other than HiveServiceHandler's roletypes.

OPSAPS-59928: INSERT INTO from SELECT using hive (hbase) table returns an error under certain conditions.

Users who upgraded to a Kerberized CDP cluster from HDP and enabled AutoTLS have reported this problem. For more information, see Cloudera Community article: ERROR: "FAILED: Execution Error, return code 2" when the user is unable to issue INSERT INTO from SELECT using hive (hbase) table.

In Cloudera Manager > TEZ > Configurations, find the tez.cluster.additional.classpath.prefix Safety Valve, and set the value to /etc/hbase/conf.

CDPD-21365: Performing a drop catalog operation drops the catalog from the CTLGS table. The DBS table has a foreign key reference on CTLGS for CTLG_NAME. Because of this, the DBS table is locked and creates a deadlock.

You must create an index in the DBS table on CTLG_NAME: CREATE INDEX CTLG_NAME_DBS ON DBS(CTLG_NAME);.

CDPD-26229: Hive TPCDS test query is timing out after 3 hours.

None.

CDPD-26556 After an upgrade, querying a CTAS table under certain conditions might throw an exception

If you upgrade your Hive cluster from CDH 6 to CDP 7, create a CTAS table in the CDP cluster from a table you upgraded from CDH, you might see the following exception when you query the new table:

class org.apache.hadoop.io.IntWritable cannot be cast to class org.apache.hadoop.hive.serde2.objectinspector.StandardUnionObjectInspector$StandardUnion        

This issue involves CDH-based tables having columns of complex types ARRAY, MAP, and STRUCT.

OPSAPS-54299 Installing Hive on Tez and HMS in the incorrect order causes HiveServer failure

You need to install Hive on Tez and HMS in the correct order; otherwise, HiveServer fails. You need to install additional HiveServer roles to Hive on Tez, not the Hive service; otherwise, HiveServer fails.

Follow instructions on Installing Hive on Tez.

CDPD-23506: OutOfMemoryError in LLAP

Long running spark-shell applications can leave sessions in interactive Hiveserver2 until the Spark application finishes (user exists from spark-shell), causing memory pressure in case of a high number of queries in the same shell (1000+).

You must close spark-shell so that sessions are closed. Add the owner of the database or the tables as a user with read or read/write access to the tables directly.

CDPD-23041: DROP TABLE on a table having an index does not work

If you migrate a Hive table to CDP having an index, DROP TABLE does not drop the table. Hive no longer supports indexes (HIVE-18448). A foreign key constraint on the indexed table prevents dropping the table. Attempting to drop such a table results in the following error:

java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails ("hive"."IDXS", CONSTRAINT "IDXS_FK1" FOREIGN KEY ("ORIG_TBL_ID") REFERENCES "TBLS ("TBL_ID"))

There are two workarounds:

• Drop the foreign key "IDXS_FK1" on the "IDXS" table within the metastore. You can also manually drop indexes, but do not cascade any drops because the IDXS table includes references to "TBLS".
• Launch an older version of Hive, such as Hive 2.3 that includes IDXS in the DDL, and then drop the indexes as described in Language Manual Indexing.

Apache Issue: Hive-24815

CDPD-20636 and DWX-6163: SHOW TABLES command does not produce a list of tables that are owned by the current user

When you run the SHOW TABLES command against a Hive Virtual Warehouse, tables are only returned if you have explicit read or read/write access to the table, or if you belong to a group that has read or read/write access. If you only have access to the tables because you are the owner of the objects, you can query the table content, but the table names do not appear in the SHOW TABLES command output.

Add the owner of the database or the tables as a user with read or read/write access to the tables directly.

CDPD-17766: Queries fail when using spark.sql.hive.hiveserver2.jdbc.url.principal in the JDBC URL to invoke Hive.

Do not specify spark.sql.hive.hiveserver2.jdbc.url.principal in the JDBC URL to invoke Hive remotely.

Workaround: specify principal=hive.server2.authentication.kerberos.principal as shown in the following syntax:

jdbc:hive://<host>:<port>/<dbName>;principal=hive.server2.authentication.kerberos.principal;<otherSessionConfs>?<hiveConfs>#<hiveVars>

HIVE-24271: Problem creating an ACID table in legacy table mode

In site-level, legacy CREATE TABLE mode, the CREATE MANAGED TABLE command might not work as expected to override the legacy behavior and create a managed ACID table. The command works only at the session level.

Workaround: Include table properties in a CREATE TABLE that specify a transactional table. For example:

CREATE TABLE T2(a int, b int) 
 STORED AS ORC
 TBLPROPERTIES ('transactional'='true');       

CDPD-13636: Hive job fails with OutOfMemory exception in the Azure DE cluster

Set the parameter hive.optimize.sort.dynamic.partition.threshold=0. Add this parameter in Cloudera Manager (Hive Service Advanced Configuration Snippet (Safety Valve) for hive-site.xml)

CDPD-16802: Autotranslate assertion failure.

The exception is not triggered when it is executed from Spark-Shell. This is from Hive in the getJdoFilterPushdownParam parameter of ExpressionTree.java, which checks the partition column as only String and not any other type.

This can be disabled by setting hive.metastore.integral.jdo.pushdown to true.

HiveServer Web UI displays incorrect data

If you enabled auto-TLS for TLS encryption, the HiveServer2 Web UI does not display the correct data in the following tables: Active Sessions, Open Queries, Last Max n Closed Queries

CDPD-11890: Hive on Tez cannot run certain queries on tables stored in encryption zones

This problem occurs when the Hadoop Key Management Server (KMS) connection is SSL-encrypted and a self signed certificate is used. SSLHandshakeException might appear in Hive logs.

Use one of the workarounds:

• Install a self signed SSL certificate into cacerts file on all hosts.
• Copy ssl-client.xml to a directory that is available in all hosts. In Cloudera Manager, in Clusters > Hive on Tez > Configuration. In Hive Service Advanced Configuration Snippet for hive-site.xml, click +, and add the name tez.aux.uris and valuepath-to-ssl-client.xml.
