--------------------------------

             Summary: RM should respect retry-interval when uses 
RetryPolicies.RETRY_FOREVER
                 Key: YARN-4113
                 URL: https://issues.apache.org/jira/browse/YARN-4113
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wangda Tan
            Priority: Critical


Found one issue in RMProxy how to initialize RetryPolicy: In 
RMProxy#createRetryPolicy. When rmConnectWaitMS is set to -1 (wait forever), it 
uses RetryPolicies.RETRY_FOREVER which doesn't respect 
{{yarn.resourcemanager.connect.retry-interval.ms}} setting.

RetryPolicies.RETRY_FOREVER uses 0 as the interval, when I run the test without 
properly setup localhost name: 
{{TestYarnClient#testShouldNotRetryForeverForNonNetworkExceptions}}, it wrote 
14G DEBUG exception message to system before it dies. This will be very bad if 
we do the same thing in a production cluster.

We should fix two places:
- Make RETRY_FOREVER can take retry-interval as constructor parameter.
- Respect retry-interval when we uses RETRY_FOREVER policy.
