Subject Re: SolrCloud shard down
Date Mon, 29 Jul 2013 16:49:10 GMT
I am using Solr 4.3.1 . I did hard commit after indexing.

I think you're right that the node was still recovering. I didn't think so
since it didn't show up as yellow "recovering" on the visual display, but
after quite a while it went from "Down" to "Active" . Thanks!
