-----------------------------------------
And a bit of a stack for searches; HOST1 is the host in question.
Note how there's not a chance of recovery but the retry logic doesn't recognise
this.
IllegalArgumentExceptions need to uprated to unrecoverable errors

> Key: HADOOP-15966
> URL: https://issues.apache.org/jira/browse/HADOOP-15966
> Project: Hadoop Common
> Issue Type: Bug
> Components: scripts
> Affects Versions: 3.0.3
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Fix For: 3.0.4, 3.2.1, 3.1.3
>
> Attachments: HADOOP-15966-001.patch
>
>
> HADOOP-8719 may have been valid at some point, but since then the world has
> moved on
> * nobody should be using Hadoop without Kerberos
> * kerberos support on java 8 + macos works just fine
> The clause to reset the java system properties is enough to stop kerberos
> working, even
> when the user is kinited in.
> Propose: remove/revert the changes. If people want it, they can set the
> options in {{HADOOP_CLIENT_OPTS}}
