During some testing of a small development cluster, one of the RegionServers
that we employ has an issue with a bad RAM stick. So when it gets into heavy
RAM operation it likes to crash. Here is my question. We had an issue where the
RegionServer holding .META. crashed. The entire cluster was unusable as it did
not reassign .META. to a different region. Also when the server goes down, what
happens to all the regions that it held? Does it reassign them to other region
servers? Also what is the correct action for recovery. It crashed during a
major_compaction so how do I verify that I am not missing data? I see that I
had 166 regions online on this server before the crash, and now after the crash
it has 158. What's the correct steps to recover HBase after a major crash?
