[jira] [Created] (HDFS-10850) getEZForPath should NOT throw FNF

Daryn Sharp created HDFS-10850:
----------------------------------

             Summary: getEZForPath should NOT throw FNF
                 Key: HDFS-10850
                 URL: https://issues.apache.org/jira/browse/HDFS-10850
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 2.8.0
            Reporter: Daryn Sharp
            Priority: Blocker


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.
