Zhe Zhang updated HDFS-9244:
----------------------------
Attachment: HDFS-9244.03.patch
Updating the patch per comments from Xiaoyu and Andrew under HDFS-9688.
I think for both movability check in general, and Trash support in specific,
what really matters is the *parent EZ* of a path. Instead of getting the EZ of
a path and checking if the EZ is equal to the path itself, we should just
directly get the parent EZ.
One caveat is whether we should allow moving the root dir of a nested EZ
itself. E.g., should {{mv /topEZ/nestedEZ /nesteEZ}} be allowed? How about we
disallow it in this initial patch, and revisit if such flexibility is asked for?
