DFSPath cache of FileStatus can become stale
--------------------------------------------
Key: HADOOP-2565
URL: https://issues.apache.org/jira/browse/HADOOP-2565
Project: Hadoop
Issue Type: Bug
Affects Versions: 0.16.0
Reporter: Doug Cutting
Fix For: 0.17.0
Paths returned from DFS internally cache their FileStatus, so that
getStatus(Path) does not require another RPC. This cache is never refreshed
and become stale, resulting in program error.
This should not be fixed until FileSystem#listStatus() is removed by
HADOOP-2563, and user code is thus no longer dependent on this cache for good
performance.
