Andrew Wang updated HDFS-10850:
-------------------------------
Attachment: HDSF-10850.001.patch
Rakesh, hope you don't mind, but I spent a little time making a new patch based
on the revert. Besides reverting, I also updated the javadoc for HdfsAdmin and
modified the test to assert the "returns null for non-existent path" behavior.
> getEZForPath should NOT throw FNF

> 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.
