Subject [jira] Commented: (HADOOP-5376) JobInProgress.obtainTaskCleanupTask() throws an ArrayIndexOutOfBoundsException
Date Wed, 04 Mar 2009 09:15:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678652#action_12678652

Vinod K V commented on HADOOP-5376:

Looked at the patch. Few comments:
 - I think the correct place for the check for setup/cleanup task is lostTaskTracker() method
itself. TIP.isRunningTask() doesn't look the correct method or atleast the correct method
 - The original TestSetupAndCleanupFailure didn't have much javadoc, can you add it in this
patch? Particularly the TestSetupAndCleanupFailure class itself, and the testWithDFS() method.
 - We can write a test simulating the exact problem in this bug using a lost tracker. We can
have this test in the same testcase - TestSetupAndCleanupFailure.
