    Description

      I got myself into a situation where I needed to truncate a massive table while it was getting hits and surprisingly the clients were not recovering. What I see in the logs is that every time we prefetch .META. we setup a new HConnection because we close it on the way out. It's awfully slow.

      We should just turn it off or make it useful. jstacks coming up.
