Fixed Issues in Cloudera Search

Review the list of Cloudera Search issues that are resolved in Cloudera Runtime 7.2.14.

CDPD-29853: Solr 8 now works in secure environments without sending OPTIONS requests during internal communication

This fix eliminates unnecessary OPTIONS requests in internal Solr communication, improving performance.

CDPD-23110: Hiveserver2/HMS hung because of the LeaseRenewer thread is waiting to get the kerberos ticket via System.in

Solr client does not overwrite ‘null’ value of javax.security.auth.useSubjectCredsOnly parameter, it only throws a warning during connection setup:

System Property: javax.security.auth.useSubjectCredsOnly set to: [true|null] not false.  
SPNego authentication may not be successful.

This may cause issues when connecting Solr to custom applications. To prevent this, you need to set

-D javax.security.auth.useSubjectCredsOnly=false

in the JVM configuration of those applications. Cloudera has implemented this change in MapReduceIndexer, CrunchIndexer, Spark-Solr, Hive-Solr connector, and Atlas.
