Subject [jira] Commented: (HADOOP-2178) Job history on HDFS
Date Fri, 11 Jan 2008 17:15:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558029#action_12558029

Runping Qi commented on HADOOP-2178:
------------------------------------


Even with hod JT, we still need to address case 3. That is,
we need a central place to store the job history files so that they can be analyzed offline.
It can be the same place in the local file system as it is now, or some common directory in
DFS.
This is in addition to the one in the output directory.

history files to the DFS.

> or
> bin/hadoop job -history <jobid>
> This will start a stand-alone jetty and load jsps
