[jira] [Commented] (HDDS-10612) Add Robot test to verify Container Balancer for RATIS containers
[ https://issues.apache.org/jira/browse/HDDS-10612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17833806#comment-17833806 ]

------------------------------------
Seems there is a intermittent failure on the acceptance test

> Currently there are only unit tests for Container Balancer and no acceptance tests at all. At a minimum, we should add a Robot test to verify Container Balancer for RATIS containers. And probably in the future we should add robot test for EC case.
> Test case:
> 1. Move 1 datanode to maintenance mode (we use 4 datanodes in this test)
> 2. Create multiple keys (after loading the data, we check that 3 datanodes are ~60% busy, and the one that is in maintenance mode is empty)
> 4. Start datanode recommission (wait until datanode recommissioning is completed)
> 5. Start container balancer (wait until container balancer is completed)
> 6. Check results (after balancing on all 4 datanodes, we should see approximately the same data distribution.)
