The "Starting a new period" line gets logged on DNs every 5 seconds with the default interval. Looks like this is because startNewPeriod is called by scanBlockPoolSlice every 5 seconds and it does an invo level log. {format} 2012-05-11 18:54:09,412 INFO org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner: Periodic Block Verification Scanner initialized with interval 504 hours for block pool BP-132016845-172.29.122.91-1336787527316. ... 2012-05-11 18:54:14,216 INFO org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner: Starting a new period : work left in prev period : 0.00% {format} -- This message is automatically generated by JIRA.
