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 2023-627: IN/OR predicate on binary column returns wrong result

An IN or an OR predicate involving a binary datatype column may produce wrong results. The OR predicate is converted to an IN due to the setting hive.optimize.point.lookup which is true by default. Only binary data types are affected by this issue. See https://issues.apache.org/jira/browse/HIVE-26235 for example queries which may be affected.
