@Montura Montura commented Apr 16, 2024

In PR for HDDS-9889 we discussed with Siddhant Sangwan that tests form org.apache.hadoop.hdds.scm.container.balancer.TestContainerBalancerTask could be refactored using MockedSCM class (introduced in HDDS-9889)

What changes were proposed in this pull request?

  1. Refactor some tests from org.apache.hadoop.hdds.scm.container.balancer.TestContainerBalancerTask
  2. Made some cleanups in org.apache.hadoop.hdds.scm.container.balancer.ContainerBalancerTask related to changes in refactored test

What is the link to the Apache JIRA

https://issues.apache.org/jira/browse/HDDS-10699

How was this patch tested?

Use standalone tests

Relating to the above comment, we would not require to call init here specifically. Similarly for all the test cases in this class.
What is the reason to remove init call within startBalancerTask?

@Tejaskriya, in some tests we do additional mock-operations for MockedSCM like here.

We have to initialize MockedSCM to do initial mocks and then add some more test-specific mocks.

I'll think how to make it better
