Subject [jira] Commented: (HADOOP-5020) JobStatus of killed JobInProgress does not carry forward start time of the Job
Date Fri, 13 Feb 2009 07:39:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673167#action_12673167
] 

Sreekanth Ramakrishnan commented on HADOOP-5020:
------------------------------------------------

I took a quick look at the patch attached. Following are comments which I had

* We are setting username in job status in this patch which was previous not set, I think
we should change the JIRA description to reflect change which is being bought by this patch.
* Test case {{testJobStatus()}}, shuts down the cluster bought up by {{TestCase.setup}} method
and starts a new cluster, we should avoid this in order to save running time.
* There is a change in JobTracker, which I think is not required for this patch.
* As far as we are testing all fields in {{JobStatus}} why don't we do a sanity check on {{JobStatus.getFinishTime()}}
once we finish a job.
* We are waiting for all {{TaskTracker}} to register with {{JobTracker}} in test case, I think
this should be moved from the test case to {{MiniMRCluster}} instead of placing it within
the test.
* Finally, a suggestion, we should slowly move all usage of {{UtilsForTests}} to {{ControlledMapReduceJob}}
and add functionality in it to control job setup and cleanup so that it can be used for testing.
I think we should discuss that in seperate JIRA.
