[jira] [Commented] (MAPREDUCE-3202) Integrating Hadoop Vaidya with Job History UI in Hadoop 2.0

["Roman Shaposhnik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13861748#comment-13861748 ] 

Roman Shaposhnik commented on MAPREDUCE-3202:
---------------------------------------------

[~vitthal_gogate] I did the first pass over the patch and it looks reasonable. Here's a few bits of feedback I've got so far:
   * I would like to suggest that an extra JIRA (perhaps a subjira of this one) gets created to track *just* the changes required in existing HS webUI to support Vaidya. One half of the patch will go there.
   * please make sure to add unit tests for that first half of the patch
   * on this JIRA we shall keep track of things under hadoop-tools/hadoop-vaidya
   * we would also need to make sure that hadoop-tools/hadoop-vaidya bits end up in maven assembly

> Hadoop Vaidya provides a detailed analysis of the M/R job in terms of various execution inefficiencies and the associated remedies that user can easily understand and fix. This Jira patch integrates it with Job History UI under Hadoop 2.0 branch.
