Jon says he's running it too.
> If re-transition to OPENING during log replay fails, server aborts. Instead,

> 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.
