Subject [jira] [Commented] (HDFS-9796) Add throttler for datanode bandwidth
Date Sat, 13 Feb 2016 08:53:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15145883#comment-15145883
] 

Lin Yiqun commented on HDFS-9796:
---------------------------------

Is it means to add the throttler in {{DataXceiver#readBlock}} and {{DataXceiver#writeBlock}}
and control the datanode io rate? And now these two methods have not limited the bandwidth.
