Subject [jira] [Created] (HBASE-16220) Demote log level for "HRegionFileSystem - No StoreFiles for" messages to TRACE
Date Tue, 12 Jul 2016 22:41:20 GMT
Andrew Purtell created HBASE-16220:

             Summary: Demote log level for "HRegionFileSystem - No StoreFiles for" messages
                 Key: HBASE-16220
                 URL: https://issues.apache.org/jira/browse/HBASE-16220
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
            Priority: Minor
             Fix For: 2.0.0, 1.4.0, 0.98.21

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.
