Description

The current audit stream close mechanism uses a Java shutdown hook registered with Hadoop's ShutdownHookManager. Solr shutdown, however, somehow does not cause the shutdown hook to be invoked, potentially resulting lost audit logs. We are experiencing lost logs toward HDFS audit destination.
