Subject [jira] [Commented] (HDFS-1740) TestNodeCount is failing with NPE
Date Mon, 27 Jun 2011 06:04:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13055343#comment-13055343
] 

Matt Foley commented on HDFS-1740:
----------------------------------

This was probably fixed by HDFS-1829, which seems to dup this bug.  Although the title of
that bug only mentions infinite loops, it also identified and resolved an NPE; see comment
