Gregory Chanan commented on SOLR-7468:
--------------------------------------
bq. About #4: Without the ticket caching support, minikdc has issues when
multiple clients try to get tickets for the same principal (from the same host).
What is a client? A thread? I looked into upgrading the hadoop minikdc
dependency a month or so back but a release wasn't ready. When I have some
time I'll look again.
bq. Also, the link to your codebase for the SolrHadoopAuthenticationFilter
seems internal as I can't get to it.
Whoops my apology! I meant:
