> 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.
