[jira] [Commented] (HBASE-23765) Use 127.0.0.1 instead of localhost when setting up Kerberos-related tests

["Bharath Vissapragada (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-23765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17026123#comment-17026123 ] 

Bharath Vissapragada commented on HBASE-23765:
----------------------------------------------

I created another jira based on my observations (HBASE-23764). I think it has something to do with ZKClient implementation (more details in the jira). I don't know if a similar problem exists with rest of the stack (hdfs/secure hdfs etc.)

> [~ndimiduk] gave an ask over on HBASE-23760 to change some of the Hadoop-level configuration properties around secure cluster setup from localhost to 127.0.0.1. He and [~bharathv] have been chasing some issues with ZooKeeper and not having a resolution of localhost to 127.0.0.1.
> Before I start making a change, how sure are we that this is an issue? Assuming that it's the nightlies that we see these on, how about we make a change to increase the krb5 and spnego debugging to see if we aren't resolving names properly?
> There might be a debug property for DNS lookups in Java too.... maybe?
