Subject Re: Region assignment after full cluster restart

bq. the assignment is not always preserved

Can you provide more information on this scenario ?
Master should have retained region assignment across cluster restart.

If you can pastebin relevant portion of master log w.r.t. the region(s)
whose location was not retained, that would be nice.

Thanks
