Subject [jira] [Commented] (HDFS-10303) DataStreamer#ResponseProcessor calculate packet acknowledge duration wrongly.
Date Tue, 10 May 2016 15:14:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15278251#comment-15278251
] 

Kihwal Lee commented on HDFS-10303:
-----------------------------------

- There is a duplicate check for the heartbeat sequence number. The inner one is no longer
necessary.
- The existing log level may not be ideal. This is directly visible to users and unless something
actually failed, it is better to log at {{INFO}}.
- I am concerned about the new test case becoming one of the flaky ones that fail when running
on a busy build machine. We need to make sure it is reliable.
