             Summary: Webhdfs retry policy for unresolved hosts
                 Key: HDFS-12784
                 URL: https://issues.apache.org/jira/browse/HDFS-12784
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Rushabh S Shah


DNs that fail to resolve the NN for the rpc connection will cause the webhdfs 
client to fail w/o retries. The webhdfs retry policy should be modified so it 
will try another DN.

Webhdfs should use RetryPolicies.retryByRemoteException in addition to the 
network FailoverOnNetworkExceptionRetry policy. The NameNodeProxies check for a 
resolved address should throw a distinct exception (like UnknownHostException) 
for the remote ex policy to catch.
