---------------------------------------
Summary: Reduce log level of PipelinePlacementPolicy failed to
create pipeline message
Key: HDDS-9204
URL: https://issues.apache.org/jira/browse/HDDS-9204
Project: Apache Ozone
Issue Type: Improvement
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
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, as its not really a warning as its a
normal occurrence.
