Known Issues in Apache Hive

Learn about the known issues in Hive, the impact or changes to the functionality, and the workaround.

CDPD-15518: ACID tables you write using the Hive Warehouse Connector cannot be read from an Impala virtual warehouse.
Read the tables from a Hive virtual warehouse or using Impala queries in Data Hub.
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)
ENGESC-2214: Hiveserver2 and HMS service logs are not deleted
Update Hive log4j configurations. Hive -> Configuration -> HiveServer2 Logging Advanced Configuration Snippet (Safety Valve) Hive Metastore -> Configuration -> Hive Metastore Server Logging Advanced Configuration Snippet (Safety Valve) Add the following to the configurations: appender.DRFA.strategy.action.type=DELETE appender.DRFA.strategy.action.basepath=${log.dir} appender.DRFA.strategy.action.maxdepth=1 appender.DRFA.strategy.action.PathConditions.glob=${log.file}.* appender.DRFA.strategy.action.PathConditions.type=IfFileName appender.DRFA.strategy.action.PathConditions.nestedConditions.type=IfAccumulatedFileCount appender.DRFA.strategy.action.PathConditions.nestedConditions.exceeds=same value as appender.DRFA.strategy.max
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.

TSB 2022-567: Potential Data Loss due to CTLT HBaseStorageHandler failure dropping underlying HBase table while rollback
If the create table target_table like source table command (CTLT) fails and the source table is HBaseStorageHandler-based table, the HBaseMetaHook rollback logic deletes the underlying HBase table, resulting in potential data loss.
Upstream JIRA
CTLT failure drops the underlying HBase table, which results in a data loss
Action required
Use external keyword explicitly in CTLT: create external table target_table like source_table;
