Subject [jira] [Created] (YARN-2947) Provide RESTful equivalent of YarnClientImpl
Date Wed, 10 Dec 2014 15:21:12 GMT
Steve Loughran created YARN-2947:

             Summary: Provide RESTful equivalent of YarnClientImpl
                 Key: YARN-2947
                 URL: https://issues.apache.org/jira/browse/YARN-2947
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: client
    Affects Versions: 2.6.0
            Reporter: Steve Loughran

For YARN clients to make effective use of this, we need an equivalent service {{YarnClientImpl}}.
The closer the REST client to this existing class (and the {{YarnClient}} API, the easier
the migration.

Requirements of SLIDER-170

* work long-haul, through proxies and security gateways like Apache Knox
* Integration with Hadoop security
* diagnostics and meaningful error messages
* ability interrupt outstanding calls

* ideally some performance metrics to track  long-haul perf issues (prefer codahale to Hadoop,
for embeddability)
* tunable restart/retry policy
