Thank you [~andrew.wang] for your time and discussions to get the consensus.
The patch looks good to me, apart from one minor checkstyle warning.

> HDFS-9433 made an incompatible change to the semantics of getEZForPath. It
> used to return the EZ of the closest ancestor path. It never threw FNF. A
> common use of getEZForPath to determining if a file can be renamed, or must
> be copied due to mismatched EZs. Notably, this has broken hive.
