Shalin Shekhar Mangar commented on SOLR-7118:
---------------------------------------------
bq. But this test doesn't need at least one replica to kill like the safe
leader test. It will kill leaders.
Look at ChaosMonkey.getRandomJetty() which calls checkIfKillIsLegal. If the
number of active shards in a slice is less than 2 then ChaosMonkey doesn't kill
a node at all.
bq. I don't know when it started happening but it looks like this test never
adds a document at all?
Answering myself, actually the FullThrottleStopableIndexingThread is only used
sometimes so the test does work but not always.
bq. Yeah, I see many request failing due to stale state and then "Not enough
nodes to handle the request". I don't think we should mark node(s) as zombies
if we exceed max retries on stale state.
This idea of mine was wrong. The node isn't being marked as a zombie i.e. it
has nothing to do with LbHttpSolrClient. There's something else at play here.
Still digging.
