Subject [jira] [Updated] (MAPREDUCE-2876) ContainerAllocationExpirer appears to use the incorrect configs
Date Fri, 07 Oct 2011 22:37:30 GMT

Anupam Seth updated MAPREDUCE-2876:

    Attachment: MAPREDUCE-2876-branch-0_23.patch

Thanks Mahadev! 

I removed also

this.monitorInterval = expireIntervel/3;



and moved it out to the subclasses to avoid the undesirable effect of silently setting a config
param that they might have set apriori in the subclass by doing something like

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug

>    Affects Versions: 0.23.0
>            Reporter: Robert Joseph Evans
>            Assignee: Anupam Seth
>            Priority: Critical

>         Attachments: MAPREDUCE-2876-branch-0_23.patch, MAPREDUCE-2876-branch-0_23.patch
> 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.
