Herman van Hovell commented on SPARK-14003:
-------------------------------------------
This is a know issue. We use a single Hive client for all sessions within a
SparkContext.
> Multi-session can not work when one session is moving files for "INSERT ...
> SELECT" clause

> 1. Start ThriftServer
> 2. beeline A connect to ThriftServer, run "INSERT INTO ... SELECT"
> 3. when beeline A job is finished and start moving files, beeline B connect
> to ThriftServer, then it will pending
> This is because we run client.loadDynamicPatitions in withHiveState, so it
