Lars Hofhansl commented on HBASE-8548:
--------------------------------------
Does this affect 0.94? The most common use case for the postOpen hook is
performing some initialization upon region open, calling this multiple time
could be bad.
> postOpen hook called twice

> postOpen hook is called twice when a region is initializing:
> Once at the end of the body of the initializeRegionInternals() method of the
> HRegion class.
> Once at the end initializeRegionStores() method of the HRegion class;
> initializeRegionStores() is called inside initializeRegionInternals() and as
> such causes the postOpen hook to be called twice.
