> In case of metastore restart hive server doesn't reopen connection to metastore. Any command gives broken pipe or similar exceptions.
> http://paste.ubuntu.com/6926215/
> Any subsequent command doesn't reestablish connection and tries to use stale (closed) connection.
> Looks like we shouldn't blindly convert any MetaException to HiveSQLException, but should distinguish between fatal exceptions and logical exceptions.
