Thanks [~hgadre]!

There's a test failure [0], due to the test introduced here, on Java 9 and 
Windows. I don't think the test code is faulty, there could be some issue with 
the test runner setup. The mailing list thread is here [1] (FYI, [~thetaphi]).

> Currently Solr kerberos authentication plugin delegates the core logic to 
> Hadoop authentication framework. But the configuration parameters required by 
> the Hadoop authentication framework are hardcoded in the plugin code itself. 
> https://github.com/apache/lucene-solr/blob/5b770b56d012279d334f41e4ef7fe652480fd3cf/solr/core/src/java/org/apache/solr/security/KerberosPlugin.java#L119
> The problem with this approach is that we need to make code changes in Solr 
> to expose new capabilities added in Hadoop authentication framework. e.g. 
> HADOOP-12082
> We should implement a generic Solr authentication plugin which will accept 
> configuration parameters via security.json (in Zookeeper) and delegate them 
> to Hadoop authentication framework. This will allow to utilize new features 
> in Hadoop without code changes in Solr.
