Subject [jira] [Created] (HDFS-3264) race in removing error edit stream could cause fatalExit()
Date Thu, 12 Apr 2012 16:25:19 GMT
race in removing error edit stream could cause fatalExit()
----------------------------------------------------------

                 Key: HDFS-3264
                 URL: https://issues.apache.org/jira/browse/HDFS-3264
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 1.1.0
            Reporter: Brandon Li
            Assignee: Brandon Li


An unhealthy storage directory and its edit stream can be removed from editStreams list. There
are multiple places to remove unhealthy directory and its stream, such as log sync, checkpointing.

Method removeEditsStreamsAndStorageDirs() could unneceissarily invoke fatalExit() if another
thread removes one error editStream before current thread. This race could be between logSync
requests, or between logSync and any place where a storage directory may be removed, e.g.,
during checkpointing.
