> Found this one running ITBLLs. We'd just finished splitting a region
> 91655de06786f786b0ee9c51280e1ee6 and then a move for it comes in. The move
> fails in an interesting way. The location has been removed from the
> regionnode kept by the Master. HBASE-20178 adds macro checks on context. Need
> to add a few checks to the likes of MoveRegionProcedure so we don't try to
> move an offlined/split parent.
