             Summary: Add datanode caching metrics
                 Key: HDFS-5320
                 URL: https://issues.apache.org/jira/browse/HDFS-5320
             Project: Hadoop HDFS
          Issue Type: Sub-task

    Affects Versions: HDFS-4949
            Reporter: Andrew Wang
            Assignee: Andrew Wang
            Priority: Minor


It'd be good to hook up datanode metrics for # (blocks/bytes) (cached/uncached/failed to cache) over different time windows (eternity/1hr/10min/1min).
