I need to double check the unit test failing, will update here only once I have the correct patch (something is hanging the region restarts). > Any thoughts on how to try to minimize the chance of us incorrectly marking a RegionServer as dead? Correct me if I'm wrong, if an unknown server join on a hbase cluster, since it's not online or dead, assignment manager should not take those `online` regions as consideration and serving request. or is this not true? Basically, `DEAD` and `UNKNOWN_SERVER` are different in branch-2 and master branch, which in ServerManager we only track `onlineServers` and `deadServer` and I didn't find any transition that a `UNKNOWN_SERVER` could be moved to `DEAD` or `ONLINE`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
