Subject [jira] Commented: (HADOOP-4191) Add a testcase for jobhistory
Date Thu, 05 Feb 2009 05:47:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12670637#action_12670637
] 

Ravi Gummadi commented on HADOOP-4191:
--------------------------------------

ok. Will validate the file name and location for both user log file and framework log file.

Currently parser would ignore the rest of the line if the pattern KEY="VALUE" is not found
somewhere on the line and will not give any errors. In this testcase we validate if the whole
line matches the expected regex.

Missed mentioning in earlier comment. For this testcase, we disable speculative execution
and see if all the attemptIDs are finished before TaskID finishes.

> 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.
