------------------------------------------------------------------
Added 01.patch with below changes.
- Added a metastore api cm_recycle to move files to CM path before trashing it.
- The destination directory is recycled in Hive.replaceFIles before trashing it.
- For insert overwrite case, oldPath and destf inputs to Hive.replaceFiles will
be same and the trashing of the files in this directory happens in
Hive.replaceFiles. So, no handling required in Hive.moveFile.
Request [~anishek] to review the patch!
