If re-transition to OPENING during log replay fails, server aborts. Instead,
should just cancel region open.

Key: HBASE-3419
URL: https://issues.apache.org/jira/browse/HBASE-3419
Project: HBase
Issue Type: Bug
Components: regionserver, zookeeper
Affects Versions: 0.90.0, 0.92.0
Reporter: Jonathan Gray
Priority: Critical
Fix For: 0.90.1, 0.92.0
The {{Progressable}} used on region open to tickle the ZK OPENING node to
prevent the master from timing out a region open operation will currently abort
the RegionServer if this fails for some reason. However it could be "normal"
for an RS to have a region open operation aborted by the master, so should just
handle as it does other places by reverting the open.
We had a cluster trip over some other issue (for some reason, the tickle was
not happening in < 30 seconds, so master was timing out every time). Because
of the abort on BadVersion, this eventually led to every single RS aborting
itself eventually taking down the cluster.
