Andrew Wang updated HDFS-7078:
------------------------------
Attachment: hdfs-7078.001.patch
It turns out that my understanding of the EZ map was off. It's actually cleaned
when the inode is removed, which happens when no snapshots reference it.
However, this means we have an issue in listEZs, since it'll list snapshot EZs
as well.
So, I added filtering in listEZ to filter out EZs that aren't present in the
current FS state. This involves re-resolving the path to check that the inode
IDs are the same.

> getEZForPath is checking if something is in an EZ based on the current
> filesystem state, rather than the snapshot filesystem state.
