> 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 inside a thread pool 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.
