------------------------------------
> HS2 retry of start has concurrency issues
> -----------------------------------------
>
> Key: HIVE-19776
> URL: https://issues.apache.org/jira/browse/HIVE-19776
> Project: Hive
> Issue Type: Improvement
> Reporter: Thejas M Nair
> Assignee: Thejas M Nair
> Priority: Major
>
> 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.
