> As part of HIVE-25990 manifest file was generated to list out the files to be
> moved. The files are moved in move task by referring to the manifest file.
> For partitioned table flow, the move is not done. This prevents the dynamic
> partition creation as the target path will be empty. As stats task needs the
> partition information, this causes the stat task to fail.
