Shalin Shekhar Mangar commented on SOLR-6956:
---------------------------------------------

Looking through the logs of the latest failure of this test at http://jenkins.thetaphi.de/job/Lucene-Solr-trunk-Linux/11802/

This test waits for all replicas of a new collection to be 'active' and then calls delete replica API with onlyIfDown=true and expects it to fail. It does this by matching the error message returned from the API call against the following string:
bq. 'with onlyIfDown='true', but state is 'active'

However, in this particular run, the API call does fail but because the OverseerCollectionProcessor finds the replica in 'recovering' state instead of 'active' and therefore the returned error message doesn't match. So the fix to the test is easy. But what's more interesting is why the OverseerCollectionProcessor couldn't see the latest cluster state when the client could. In the logs too, I can see watchers being fired on the new cluster state before the call to delete replica is made. I'll dig a bit more before I commit a fix to the test.
