Description

By default hive is using hive.exec.submit.local.task.via.child as true. In this case all MR tasks are running in separate processes and in this case NPE is thrown from PhoenixStorageHandler.getTableKeyOfSession. The reason is that in new process the SessionState returns null and method is unable to build key for session. We need to pass session id through jobConf.
