stack commented on HBASE-20881:
-------------------------------
Interesting. I'd think we could do faster than 500 regions in 7min. [~busbey]
added nice 'machine' output so could get list of processes, load, etc., so
could tell if machine was struggling or not. Here it is for nightly
branch-2.0...

You can get same for nightly. It does not seem to be on the flakey run
though... which makes sense... I suppose. So, slow assign messes up the test?
Make it 100 regions instead of 500?

> Now have an AssignProcedure, an UnssignProcedure, and also a
> MoveRegionProcedure which schedules an AssignProcedure and an
> UnssignProcedure to move a region. This makes the logic a bit complicated, as
> MRP is not a RIT, so when SCP can not interrupt it directly...
