Description

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.
