Subject Re: [jira] [Closed] (BLUR-342) Support full cluster operations on random ports
Date Wed, 17 Sep 2014 16:28:10 GMT
Before we had discussed the possiblity of having a configuration that
would state how many shards/controllers etc there are expected to be.
That way we could at least alert if the number drops below expected.
Has that piece been done?
