[jira] [Created] (HDFS-14981) BlockStateChange logging is exceedingly verbose

Nick Dimiduk created HDFS-14981:
-----------------------------------

             Summary: BlockStateChange logging is exceedingly verbose
                 Key: HDFS-14981
                 URL: https://issues.apache.org/jira/browse/HDFS-14981
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: logging
            Reporter: Nick Dimiduk


On a moderately loaded cluster, name node logs are flooded with entries of {{INFO BlockStateChange...}}, to the tune of ~30 lines per millisecond. This provides operators with little to no usable information. I suggest reducing this log message to {{DEBUG}}. Perhaps this information (and other logging related to it) should be directed to a dedicated block-audit.log file that can be queried, rotated on a separate schedule from the log of the main process.
