[jira] [Created] (HDFS-2229) Deadlock in NameNode

Deadlock in NameNode
--------------------

                 Key: HDFS-2229
                 URL: https://issues.apache.org/jira/browse/HDFS-2229
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli


Either I am doing something incredibly stupid, or something about my environment is completely weird, or may be it really is a valid bug. I am running a NameNode deadlock consistently with 0.23 HDFS. I could never start NN successfully.

Hi,

I posted a patch a few days back.  Jitendra and Todd are reviewing it.  Hopefully, the bug can be fixed soon.

Gang,

 Can we please get some b/w on this one? This is really critical and blocking our ability to anything with HDFS from trunk for MR-279.

thanks,
