Subject [jira] [Commented] (MAPREDUCE-2322) Throw better error message when malformed filenames in history dir
Date Wed, 18 May 2011 21:58:47 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13035730#comment-13035730

Todd Lipcon commented on MAPREDUCE-2322:

Hi Albert. A few comments:
- maybe it would make sense to move these methods and the PathFilter implementation into JobHistory.java?
Then it would be really easy to write unit tests for them.
- looks like there is a hard tab character in the patch. Our code convention is to use spaces
rather than tabs. Can you make sure your editor is setup for that?

> I've occasionally seen an IndexOutOfBoundsException visiting jobhistory.jsp because some
file makes it into the history log directory. We should filter these out and throw a more
useful exception if a malformed one somehow makes it to the comparator
