Subject [jira] [Created] (YARN-7429) Auxillary Service status on NodeManager UI / Cli
Date Thu, 02 Nov 2017 09:24:02 GMT
Prabhu Joseph created YARN-7429:
-----------------------------------

             Summary: Auxillary Service status on NodeManager UI / Cli
                 Key: YARN-7429
                 URL: https://issues.apache.org/jira/browse/YARN-7429
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph
            Priority: Major


When Auxillary services like Spark Shuffle , MapReduce Shuffle Service fails for some reason,
and the jobs running will have issue when the remote containers tries to fetch the data from
the Node where service is failed to initialize.

Reason shuffle service failed to start will be in NodeManager logs during startup and likely
will be lost after few days when we noticed the jobs failing. Useful if NodeManager UI / Cli
shows the list of Auxillary Services and their status and capture any error message if it
has failed.
