tomscut created HDFS-16371:
------------------------------

             Summary: Exclude slow disks when choosing volume
                 Key: HDFS-16371
                 URL: https://issues.apache.org/jira/browse/HDFS-16371
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: tomscut
            Assignee: tomscut


Currently, the datanode can detect slow disks. When choosing volume, we can exclude these slow disks according to some rules. This will prevents some slow disks from affecting the throughput of the whole datanode.
