   Thanks @sky76093016 for your analysis.
   The intermittent failures in this test case appear to be related to the HDDS-4710.
   In the current pipeline placement policy, nodes are sorted based on pipeline counts of each node when filtering viable nodes ([refer](https://github.com/apache/ozone/blob/996518a47f97abdfe29d80aa0982ae51c84095b5/hadoop-hdds/server-scm/src/main/java/org/apache/hadoop/hdds/scm/pipeline/PipelinePlacementPolicy.java#L127)).
   I think that even if the nodes are selected randomly, the nodes with less load should be selected first.
