Subject [jira] [Commented] (HDFS-5317) Go back to DFS Home link does not work on datanode webUI
Date Mon, 07 Oct 2013 23:46:42 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13788718#comment-13788718

Haohui Mai commented on HDFS-5317:
----------------------------------

There are no obvious reasons that the sleep is required. Because the JSP page runs in a different
thread, the information is never guaranteed to be up-to-date, in which case putting a sleep()
in the JSP page would not help.

Alternatively, we can make the page faster, and the user always has the freedom to refresh
the page when needed.
