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}}".
