Description
HDFS-6836 made datanode read request logging DEBUG. There is a good reason why it was at INFO for so many years. This is very useful in debugging load issues. This jira will revert HDFS-6836.
We haven't seen it being a bottleneck on busy hbase clusters, but if someone thinks it is a serious overhead, please make it configurable in a separate jira.
