Description

HS2 starts the thrift binary/http servers in background, while it proceeds to do other setup (eg create zookeeper entries). If there is a ZK error and it attempts to stop and start in the retry loop within HiveServer2.startHiveServer2, the retry fails because the thrift server doesn't get stopped if it was still getting initialized.

The thrift server initialization and stopping needs to be synchronized.
