----------------------------------
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.
