             Summary: Adding more slow action log in critical read path
                 Key: HDFS-8439
                 URL: https://issues.apache.org/jira/browse/HDFS-8439
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Liu Shaohui
            Assignee: Liu Shaohui
            Priority: Minor


To dig a HBase read spike issue, we'd better to add more slow pread/seek log in read flow
to get the abnormal datanodes.

Patch will be uploaded soon.
