Lars Hofhansl commented on HBASE-2611:
--------------------------------------
Yeah, I don't know.
But what can happen is that the region server who wins the race to take over
the dead region server's queues could die before it even manages to call multi.
In the case - since the ephemeral znode is only removed once - we won't ever
retry to move that region server's queues again. Right?
So another part of the puzzle is to have a way to retry the takeover later.
Back in the comments here there are various suggestions about how to do that
mostly centering around having all surviving RSs try to move a dead RS's queues.
