Subject [jira] [Commented] (YARN-1109) Consider throttling or demoting NodeManager "Sending out status for container" logs
Date Mon, 28 Oct 2013 09:01:37 GMT

    [ https://issues.apache.org/jira/browse/YARN-1109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13806634#comment-13806634
] 

Sandy Ryza commented on YARN-1109:
----------------------------------

One tiny nitpick:
{code}
+      if (LOG.isDebugEnabled()){
{code}
There should be a space between the closing parentheses and the curly brace.

Other than that, the patch looks good to me.

> Diagnosing NodeManager and container launch problems is made more difficult by the enormous
number of logs like
> {code}
> Sending out status for container: container_id {, app_attempt_id {, application_id {,
id: 18, cluster_timestamp: 1377559361179, }, attemptId: 1, }, id: 1337, }, state: C_RUNNING,
diagnostics: "Container killed by the ApplicationMaster.\n", exit_status: -1000
> {code}
> On an NM with a few containers I am seeing tens of these per second.
