Elliott Clark created HADOOP-12421:
--------------------------------------

             Summary: Add jitter to RetryInvocationHandler
                 Key: HADOOP-12421
                 URL: https://issues.apache.org/jira/browse/HADOOP-12421
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Elliott Clark
            Assignee: Elliott Clark


Calls to NN can become synchronized across a cluster during NN failover. This leads to a spike in requests until things recover. Making an already tricky time worse.
