{quote} Perhaps the previous host did clean shutdown? If it did not, perhaps
this is where we went awry.. we are skipping recovery of hbase:meta?
{quote}
The cluster was restarted at 2018-05-30 04:26:27,895. It _should_ have been
done gracefully, but I'm not sure if I can determine that anymore (if the
process takes more than like 30 or 60s, I think the graceful stop is followed
up with a {{kill}}).

> Another bug coming out of a master restart and replay of the pv2 logs.
> The master merged two regions into one successfully, was restarted, but then
> ended up assigning the children region back out to the cluster. There is a
> log message which appears to indicate that RegionStates acknowledges that it
> doesn't know what this region is as it's replaying the pv2 WAL; however, it
> incorrectly assumes that the region is just OFFLINE and needs to be assigned.
