Mark Miller commented on SOLR-7118:
-----------------------------------

bq.  The failures due to the full throttle test 

I have some other improvements for this test in the issue around a down shard 
still being able to elect a leader. Not sure if they overlap. There are a 
couple problems (like the concurrent solr server shutting down the http 
connection pool early sometimes). I'll try and pull them out eventually.

bq. Chasing such false negatives wastes too much time and energy.

It's part of making this test good unfortunately. You don't get good 
complicated tests without a lot of effort. And this is a very complicated 
integration test. Given the low effort that has gone into these tests, there is 
still a lot of time and energy that they will suck before they are good. They 
are the most critical tests we have in SolrCloud and also some of the least 
mature.
