             Summary: HDFS Slow disk detection
                 Key: HDFS-7896
                 URL: https://issues.apache.org/jira/browse/HDFS-7896
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: datanode
            Reporter: Arpit Agarwal

HDFS should detect slow disks. To start with we can flag this information via the NameNode
web UI. Alternatively DNs can avoid using slow disks for writes.
