Behavioral Changes in Apache Solr

Learn about the change in certain functionality of Apache Solr that has resulted in a change in behavior from the previously released version to this version of Cloudera Runtime.

Validation of parameter changed in Solr client
Previous behavior:

Unless explicitely set to 'true', Solr client used to set the value of parameter to 'false'.

New behavior:

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

System Property: 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, set

in the JVM configuration of those applications.

Cloudera has implemented this change in MapReduceIndexer, CrunchIndexer, Hive-Solr connector, and Atlas.
