Subject [jira] [Commented] (YARN-4216) Container logs not shown for newly assigned containers after NM recovery
Date Mon, 05 Oct 2015 09:21:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-4216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14943113#comment-14943113
] 

Bibin A Chundatt commented on YARN-4216:
----------------------------------------

{quote}
That's why YARN-1362 was done, so we can explicitly tell the nodemanager whether or not the
NM is under supervision and likely to restart.
{quote}
*yarn.nodemanager.recovery.supervised=false* in my current setup.
In this case as i understand from above comment i am supposed to set *yarn.nodemanager.recovery.supervised*
as true to inform restart is under supervision.
 
[~jlowe] so should i close this jira ??

> # Submit pi job with 20 maps 
> # Once 5 maps gets completed in NM 1 stop NM (yarn daemon stop nodemanager)
> (Logs of all completed container gets aggregated to HDFS)
> # Now start  the NM1 again and wait for job completion
> *The newly assigned container logs on NM1 are not shown*
> *hdfs log dir state*
> # When logs are aggregated to HDFS during stop its with NAME (localhost_38153)
> # On log aggregation after starting NM the newly assigned container logs gets uploaded
with name  (localhost_38153.tmp) 
> History server the logs are now shown for new task attempts
