Subject [jira] Updated: (HADOOP-4530) In fsck, HttpServletResponse sendError fails with IllegalStateException
Date Tue, 04 Nov 2008 19:22:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hairong Kuang updated HADOOP-4530:
----------------------------------

    Attachment: fsckError2.patch

The patch incorporates Konstantin's comments. Thank Konstantin for helping me figure out the
way to test the failure case.

In addition, it makes sure that the DFS cluster gets shutdown in case of a failure in the
testFsckCorrupt.
