Date Thu, 11 Jun 2009 04:59:08 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-5921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat updated HADOOP-5921:
-------------------------------

    Attachment: HADOOP-5921-v2.4.patch

Attaching a patch that fixes the issue. This patch does the following
# keeps on creating _jobtracker.info_ file in jobtracker.offerService() until it gets created
successfully
# adds a testcase to test this bug.

Result of test-patch[exec] +1 overall.  
     [exec] 
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec] 
     [exec]     +1 tests included.  The patch appears to include 3 new or modified tests.
     [exec] 
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec] 
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
warnings.
     [exec] 
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec] 
     [exec]     +1 Eclipse classpath. The patch retains Eclipse classpath integrity.
     [exec] 
     [exec]     +1 release audit.  The applied patch does not increase the total number of
release audit warnings.

Note that if the jobtracker.info file is garbled then the jobtracker simply comes out as expected.

Running ant test now.
