> Messages like this can significantly accumulate in regionserver logs when a cluster is
carrying empty tables. 
> > 2016-07-07 15:59:59,994 DEBUG [region-location-1] regionserver.HRegionFileSystem
- No StoreFiles for: hdfs://pod/hbase/data/default/table/region/family 
> All this means is no data has been written into a region yet. Table utilization information
can be collected by other means for managing that. Because many deployments run with DEBUG
as the default log level, especially when trying to track down other production issues, this
message is better logged at TRACE level.
