-------------------------------------
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}}.
