Subject [jira] [Updated] (HDFS-4374) Display NameNode startup progress in UI
Date Wed, 27 Mar 2013 21:29:16 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4374?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated HDFS-4374:
--------------------------------

    Attachment: HDFS-4374.1.patch

I'm attaching a patch that changes dfshealth.jsp to display the startup progress information
that was tracked in HDFS-4372.  I also needed to add some checks to prevent attempting to
access the FSNamesystem or the RPC server before they get initialized.  This is a consequence
of starting the NameNode HTTP server earlier in the startup sequence.  (Those changes are
in HDFS-4372.)

I'm not clicking Submit Patch yet, because this patch is dependent on the HDFS-4372 patch.
