Description

In case if old Hive z-nodes were already de-registered and user wanted to issue additional restarts with "upgrade restart" flag (for example during upgrade pause) - the command could fail as old z-nodes would be already de-registered.

Execution of 'hive --config /usr/hdp/current/hive-server2/conf/conf.server --service hiveserver2 --deregister x.x.xxxx.x.x.x.xxx-x' returned 255. log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender.
Error deregistering HiveServer2 instances for version: x.x.xxxx.x.x.x.xxx-x from ZooKeeper.org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /hiveserver2-sdm

The upgrade restart functionality for Hive should be enchanted to support this behaviour
