Subject [jira] Updated: (HADOOP-4288) java.lang.NullPointerException is observed in Jobtracker log while call heartbeat
Date Mon, 29 Sep 2008 10:02:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4288?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hemanth Yamijala updated HADOOP-4288:
-------------------------------------

    Priority: Blocker  (was: Major)

Promoting to a blocker based on current diagnosis. This is a clear bug in the code that will
result in this error whenever users run more than one jobs, assuming HADOOP-4053 is fixed.
