[jira] Updated: (HADOOP-2565) DFSPath cache of FileStatus can
become stale
[ https://issues.apache.org/jira/browse/HADOOP-2565?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Chansler updated HADOOP-2565:
------------------------------------
Fix Version/s: (was: 0.17.0)
> DFSPath cache of FileStatus can become stale
> --------------------------------------------
>
> Key: HADOOP-2565
> URL: https://issues.apache.org/jira/browse/HADOOP-2565
> Project: Hadoop Core
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.16.0
> Reporter: Doug Cutting
>
> 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.
