             Summary: TestStochasticLoadBalancer has some slow methods, and inconsistent set, reset, unset of configuration
                 Key: HBASE-26989
                 URL: https://issues.apache.org/jira/browse/HBASE-26989
             Project: HBase
          Issue Type: Test
          Components: Balancer, test
    Affects Versions: 2.0.0, 3.0.0-alpha-1
            Reporter: David Manning
            Assignee: David Manning


Some test ordering issues were exposed by adding new tests in HBASE-22349. I think this is a legitimate issue which is tracked in HBASE-26988.

But we can update the tests to be consistent in how they update configuration to reduce confusion, removing the {{unset}} calls.

We can also update other configuration values to significantly speed up the long-running methods. Methods that are simply checking for balancer plans do not need to {{runMaxSteps}}. All we need to do is run enough steps to guarantee we will plan to move one region. That can be far fewer than the tens of millions of steps we may be running given {{runMaxSteps}}.
