[jira] [Created] (HDFS-3504) Configurable retry in DFSClient

Siddharth Seth created HDFS-3504:
------------------------------------

             Summary: Configurable retry in DFSClient
                 Key: HDFS-3504
                 URL: https://issues.apache.org/jira/browse/HDFS-3504
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.0-alpha, 1.0.0
            Reporter: Siddharth Seth


When NN maintenance is performed on a large cluster, jobs end up failing. This is particularly bad for long running jobs. The client retry policy could be made configurable so that jobs don't need to be restarted.
