> This case caused when hue request twice GetSchema with same sessionHandler
> in same time.
> (hue use same session handle to same hue username)
> I found the thread-unsafe situation in hive session's metastore client access
> code.
> so i patched my hive's HiveSessionImpl.java and HiveMetaStoreClient.java to
> synchronize metastore client instance.
> How do you think about this patch applying to hive?
