Subject [jira] [Commented] (HDFS-2229) Deadlock in NameNode
Date Tue, 09 Aug 2011 04:28:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081428#comment-13081428
] 

Vinod Kumar Vavilapalli commented on HDFS-2229:
-----------------------------------------------

bq. Any idea why the MR cluster launches are triggering this issue reliably but the HDFS tests
are passing fine? (when they launch hundreds of miniclusters)
My setup is trunk code with security enabled on a real cluster (not single node).

I haven't had time to run it again with the attached patch. Will report soon once I get around
to it.

> 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.
