Ashutosh Chauhan resolved HIVE-3324.
------------------------------------

    Resolution: Invalid

You can't use derby for this, since a remote daemon is required to be running which is accessible to all task nodes. Derby runs in embedded mode, so that won't work. You need mysql or orther RDBMS running as daemon and accessible from all task nodes.
