Restart of HiveServer2 and Knox
Problem: HS2 failover requires knox restart if cookie use is enabled for HS2
Description: When HiveServer2 is accessed via Knox Gateway and HiveServer2 has cookie-based authentication enabled, a HiveServer2 restart requires that Knox also be restarted to get Knox-HiveServer2 interaction working again.
Workaround: Set hive.server2.thrift.http.cookie.auth.enabled=false in hive-site.xml in Ambari.
