Maksim Myskov updated HDDS-11503:
---------------------------------
Description:
Currently there is a robot test for container balancer for RATIS container. We
should add robot test for EC case as well.
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.)
was:
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.

1. Move 1 datanode to maintenance mode (we use 4 datanodes in this test)
