> The HiveServer2’s server handler can switch to process the operation from
> other session, in such case, the Hive cached in ThreadLocal is not the same
> as the Hive in SessionState, and can be referenced by another session.
> If the two handlers swap their sessions to process the DatabaseMetaData
> request, and the HiveMetastoreClientFactory obtains the Hive via Hive.get(),
> then there is a chance that the deadlock can happen.
