Subject [jira] [Commented] (MAPREDUCE-2876) ContainerAllocationExpirer appears to use the incorrect configs
Date Fri, 26 Aug 2011 15:30:29 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2876?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13091825#comment-13091825

Mahadev konar commented on MAPREDUCE-2876:
------------------------------------------

bobby,
  I think we can leave the setMonitor API. I was saying something along the lines of:

When creating NMLivenessMonitor:

{code}

monitor.setExpiry(x);
monitor.setMonitorInternval(x/3);

{code}

So in case someone wants to use Livenessmonitor with almost the same interval as expiry can
use it that way. Seems reasonable?

> ContainerAllocationExpirer sets the expiration interval to be RMConfig.CONTAINER_LIVELINESS_MONITORING_INTERVAL
but uses AMLIVELINESS_MONITORING_INTERVAL as the interval.  This is very different from what
AMLivelinessMonitor does.
> There should be two configs RMConfig.CONTAINER_LIVELINESS_MONITORING_INTERVAL for the
monitoring interval and RMConfig.CONTAINER_EXPIRY_INTERVAL for the expiry.
