             Summary: Ozone: Reduce some KSM/SCM deletion log messages from INFO to DEBUG
                 Key: HDFS-12471
                 URL: https://issues.apache.org/jira/browse/HDFS-12471
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Xiaoyu Yao


Looks like we are logging a few no-op messages every minute in KSM/SCM log. 
Should we reduce the log level to DEBUG or TRACE? cc: [~anu],[~cheersyang], [~yuanbo].
