[jira] [Created] (HDFS-6307) Case Sensitivity issue with Client and HA configuration

Dave Marion created HDFS-6307:
---------------------------------

             Summary: Case Sensitivity issue with Client and HA configuration
                 Key: HDFS-6307
                 URL: https://issues.apache.org/jira/browse/HDFS-6307
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.4.0
         Environment: Hadoop 2.4.0
HA NN Configuration
            Reporter: Dave Marion


If you create a configuration based off of the example at [1], but you use the nameservice MyCluster instead of mycluster, the Client will throw an UnknownHostException if you try to use hdfs://mycluster. I believe this works in a non-HA configuration.
