Description

Currently, the thread created by AsyncAuditProvider can wait upto 30 seconds before exiting during shutdown. This behavior is due to the mechanism used to notify the audit thread to quit - a flag set by the thread that signals to quit.

Update this implementation to use Thread.interrupt() call, which will result in InterruptedException in the audit thread. This will ensure that the audit thread will not delay shutdown of the process (like namenode, hbase-servers, hive-server, etc).
