Subject [jira] Created: (HADOOP-2565) DFSPath cache of FileStatus can become stale
Date Wed, 09 Jan 2008 18:54:34 GMT
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.
