Subject [jira] Commented: (HADOOP-3204) LocalFSMerger needs to catch throwable
Date Wed, 09 Apr 2008 18:29:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12587291#action_12587291
] 

Chris Douglas commented on HADOOP-3204:
---------------------------------------

{code}
    public synchronized Throwable getFailureCause() {
      return mergeThrowable == null ? null : mergeThrowable;
    }
{code}

Is equivalent to "return mergeThrowable". The synchronization is probably unnecessary for
the get.

LocalFSMerger thread.
> Does it have the same problem as HADOOP-3154?
