[jira] [Created] (HDFS-7258) CacheReplicationMonitor rescan schedule log should use DEBUG level instead of INFO level

Xiaoyu Yao created HDFS-7258:
--------------------------------

             Summary: CacheReplicationMonitor rescan schedule log should use DEBUG level instead of INFO level
                 Key: HDFS-7258
                 URL: https://issues.apache.org/jira/browse/HDFS-7258
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.6.0
            Reporter: Xiaoyu Yao
            Priority: Minor


CacheReplicationMonitor rescan scheduler adds two INFO log entries every 30 seconds to HDSF NN log as shown below. This should be a DEBUG level log to avoid flooding the namenode log.
