> Look at HIVE-3106 for details.
> In order to make sure that concurrency is not an issue for multi-table
> inserts, the current option is to introduce a dependency task, which thereby
> delays the creation of all partitions. It would be desirable to release the
> locks for the outputs as soon as the move task is completed. That way, for
> multi-table inserts, the concurrency can be enabled without delaying any
> table.
> Currently, the movetask contains a input/output, but they do not seem to be
> populated correctly.
