> Key: HIVE-26467
> URL: https://issues.apache.org/jira/browse/HIVE-26467
> Project: Hive
> Issue Type: Improvement
> Reporter: Syed Shameerur Rahman
> Assignee: Syed Shameerur Rahman
> Priority: Major
> Fix For: 4.0.0
>
>
> Currently SessionState.get() returns null if it is called inside a
> ThreadPool. If there is any custom third party component leverages
> SessionState.get() for some operations like getting the session state or
> session config it will result in null since session state is thread local
> (https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/session/SessionState.java#L622)
> and ThreadLocal variable are not inheritable to child threads / thread pools.
> So one solution is to make the thread local variable inheritable so the
> SessionState gets propagated to child threads.
