> Since removal of master logging of all rows of catalog tables, there is a
> hole when it comes to debugging what happened in hbase at some time in the
> past. The region historian is the place we keep up region history only we've
> been deleting old history when region is deleted. Instead, lets not delete
> region history but keep it around a while, say a week. Also, keep all
> versions -- currently its set to 1.
> To do this, may need to also so HBASE-998.
