Subject [jira] [Created] (HDFS-12784) Webhdfs retry policy for unresolved hosts
Date Mon, 06 Nov 2017 20:38:00 GMT
Rushabh S Shah created HDFS-12784:

             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.
