Subject [jira] Created: (MAPREDUCE-2029) DistributedRaidFileSystem not removed from cache on close()
Date Wed, 25 Aug 2010 00:33:19 GMT
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


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.
