Enis Soztutar updated HBASE-10661:
----------------------------------
Attachment: hbase-10661_v2.patch
Attaching a v2 patch, since we still see some failures after v1 patch.
This patch adds another candidate generator which is trying to move away the
regions which are co-located in the same rack. This will help with the test as
well as the production cases because the LB is expected to converse sooner.
> TestStochasticLoadBalancer.testRegionReplicationOnMidClusterWithRacks() is
> flaky

> One of the tests introduced in HBASE-10351 seems to be flaky. The LB cannot
> compute the fully assignment plan in time when there are racks and region
> replicas for the test, so it is failing sometimes.
> We can reduce the computation amount, and increase the LB runtime to make the
> test stable.
