Subject [jira] Commented: (HADOOP-1733) LocalJobRunner uses old-style job/tip ids
Date Thu, 25 Oct 2007 17:59:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12537672
] 

Doug Cutting commented on HADOOP-1733:
--------------------------------------

I don't see a need for job ids to be identical between localrunner and jobtracker.  User code
should not rely on the format of job ids.  Having them different helps enforce that!  We should
never parse job ids, but only require them to be sufficiently unique.

So we should change the format of localrunner's job ids if they're not sufficiently unique.
 I'm aware of no bugs resulting from localrunner job id clashes.  If any arise, then we might
revisit this issue, otherwise I think we should resolve this as "won't fix".
