Junping Du updated YARN-4430:
-----------------------------
Target Version/s: (was: 2.8.0)
> registry security validation can fail when downgrading to insecure would work
> -----------------------------------------------------------------------------
>
> Key: YARN-4430
> URL: https://issues.apache.org/jira/browse/YARN-4430
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn
> Affects Versions: 2.7.1
> Environment: Kerberos, java 7 & 8
> Reporter: Steve Loughran
>
> The Registry ZK client code does a pre-emptive validation of registry
> security settings, in the interest of being helpful when things fail.
> But: sometimes it fails fast (see stack trace in SLIDER-993) when it could
> just warn and continue -because if the registry is only being read, skipping
> SASL auth works
