Rohith Sharma K S commented on YARN-6409:
-----------------------------------------
bq. Do you mean to say there is NO way to remove blacklisted nodes from AM
container?
Yup
bq. RM will often try the subsequent AM launch attempts on the same node and
fail the application eventually,
Do you mean NM is unresponsive but NM heartbeats are sent to RM?
> RM does not blacklist node for AM launch failures

> Key: YARN-6409
> URL: https://issues.apache.org/jira/browse/YARN-6409
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 3.0.0-alpha2
> Reporter: Haibo Chen
> Assignee: Haibo Chen
> Attachments: YARN-6409.00.patch, YARN-6409.01.patch
>
>
> Currently, node blacklisting upon AM failures only handles failures that
> happen after AM container is launched (see
> RMAppAttemptImpl.shouldCountTowardsNodeBlacklisting()). However, AM launch
> can also fail if the NM, where the AM container is allocated, goes
> unresponsive. Because it is not handled, scheduler may continue to allocate
> AM containers on that same NM for the following app attempts.
