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.
