> DistributedRaidFileSystem not removed from cache on close()
> -----------------------------------------------------------
>
> Key: MAPREDUCE-2029
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2029
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/raid
> Affects Versions: 0.22.0
> Reporter: Paul Yang
> Assignee: Ramkumar Vadali
> Attachments: MAPREDUCE-2029.patch
>
>
> When DistributedRaidFileSystem.close() is called, it does not remove itself
> from the FileSystem cache, but it does close the underlying filesystem, e.g.
> DFS.
> Because the DRFS with the closed DFS is still in the cache, calling
> FileSystem.get() returns a stale DRFS that throws 'filesystem closed'
> exceptions.
