Subject [jira] Commented: (HADOOP-4191) Add a testcase for jobhistory
Date Tue, 17 Feb 2009 12:18:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674191#action_12674191

Amar Kamat commented on HADOOP-4191:
------------------------------------

bq. Some comments:
5. Also check if the time is sane. START_TIME = 0 doesnt make any sense (see HADOOP-5276).
Also make sure that FINISH_TIME > START_TIME for each attempt, task and job.

> Add a testcase for jobhistory

> Changes in job history might break the history parser which in turn might break some
features like jobtracker-recovery, history-viewer etc. There should be a testcase that catches
these incompatible changes early and informs about the expected change.
