I'm not sure if we want to discuss here or on #2114, but, copying from https://github.com/apache/hbase/pull/2114#pullrequestreview-452770911, > While I think the CatalogJanitor approach is probably an effective solution, I wonder if there's a "faster" solution we could do. > The main question is, when we don't have ZooKeeper telling us that a RegionServer has died, how can we be certain that a RegionServer won't "come back"? If we get into a situation where data was still hosted on a RegionServer we thought was dead, we would double-assign the region and that'd be a big bug. > Any thoughts on how to try to minimize the chance of us incorrectly marking a RegionServer as dead? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
