[jira] [Created] (HDFS-4494) Confusing exception for unresolvable hdfs host with security enabled

Daryn Sharp created HDFS-4494:
---------------------------------

             Summary: Confusing exception for unresolvable hdfs host with security enabled
                 Key: HDFS-4494
                 URL: https://issues.apache.org/jira/browse/HDFS-4494
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.0.0-alpha, 0.23.0, 3.0.0
            Reporter: Daryn Sharp


{noformat}
$ hadoop fs -ls hdfs://unresolvable-host
ls: Can't replace _HOST pattern since client address is null
{noformat}

It's misleading because it's not even related to the client's address.  It'd be a bit more informative to see something like "{{UnknownHostException: unresolvable-host}}".
