Subject [jira] [Commented] (MAPREDUCE-5933) Enable MR AM to post history events to the timeline server
Date Sat, 23 Aug 2014 00:04:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5933?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14107736#comment-14107736

Robert Kanter commented on MAPREDUCE-5933:

I'll fix the javac warnings and look into the test timeout next week (the release audit is
again not from this patch)

{quote}Robert Kanter, Appoligies for not responding earlier to this JIRA. I've posted my design
requests to MAPREDUCE-5858 to make sure existing can be kept happy.{quote}
My patch doesn't affect the JHS in any way.  It simply makes the AM push the events to the
ATS in addition to the file that the JHS gets; and if the ATS is disabled, there should be
no affect.  So I think this meets your requests.

> Nowadays, MR AM collects the history events and writes it to HDFS for JHS to source.
With the timeline server, MR AM can put these events there.
