Subject [jira] [Commented] (YARN-6521) Yarn Log-aggregation Transform Enable not to Spam the NameNode
Date Wed, 26 Apr 2017 18:25:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-6521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15985307#comment-15985307
] 

Robert Kanter commented on YARN-6521:
-------------------------------------

[~djp], having policies for that is kind of what I was getting at in YARN-6356.  YARN-6356
suggests adding a separate retain-seconds config for succeeded jobs vs failed jobs so you
could, for example, keep succeed job logs for 1 day (because you don't really care about them)
and failed job logs for 1 week (because you need time to look at them).  But generalizing
that to be more flexible is a good idea.

> Nowdays We have large cluster,with the apps incr and container incr ,We split an  namespace
to store applogs. 
> But the  log-aggregation /tmp/app-logs incr also make the namespace responce slow.  
> We want to chang yarn.log-aggregation-enable true -> false,But Transform the the yarn
log cli service also can get the app-logs.
