Eli Collins created HDFS-3410:
---------------------------------
Summary: BlockPoolSliceScanner is too chatty
Key: HDFS-3410
URL: https://issues.apache.org/jira/browse/HDFS-3410
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Eli Collins
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.
