Subject [jira] Commented: (HADOOP-4017) Unify the way job history filename is parsed
Date Fri, 24 Oct 2008 08:43:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12642413#action_12642413
] 

Amar Kamat commented on HADOOP-4017:
------------------------------------

Two things missing
1) The case where the _username_/_jobname_ contains a '_'.
2) Test case.

> Job history filename has the following meta-info :
> - jobtracker's hostname
> - job id
> - username
> - jobname
> {{HistoryViewer.java}} and {{jobhistory.jsp}} are required to parse the history filename
to extract the meta-info. It makes more sense to provide a common utility in {{JobHistory}}
to do it.
