Stephen O'Donnell updated HDDS-9204:
------------------------------------
Description:
Under normal circumstances, a log like this is seen frequently in the SCM log:
{code}
2023-08-23 10:41:06,087 [main] WARN pipeline.PipelinePlacementPolicy
(PipelinePlacementPolicy.java:filterViableNodes(166)) - Pipeline creation
failed due to no sufficient healthy datanodes. Required 3. Found 2. Excluded 14.
{code}
This happens regularly, as the background pipeline creator thread attempts to
fill all datanodes with pipelines. When all the limits have been reached the
above scenario legitimately happens and prints the warning to the logs.
We should move this message to debug along with a few others similar to it, as
they are not warnings, but normal occurrences.

above scenario legitimately happens and prints the warning to the logs.
We should move this message to debug, as its not really a warning as its a
normal occurrence.
