Subject [jira] [Commented] (HDFS-1734) 'Chunk size to view' option is not working in Name Node UI.
Date Thu, 24 Mar 2011 10:06:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010620#comment-13010620

Uma Maheswara Rao G commented on HDFS-1734:

Thanks Jithendra for Review,
 Here this fix will solve this problem, because When we click on the file name in NN UI, generateFileDetails
will write all the parameters in to page as hidden.

out.print("<input type=\"*hidden*\" name=\"genstamp\" value=\"" + *genStamp*
+	+ "\">")

 When we click refresh, the same parameters will be resubmitted. 

The initial problem is, when we click on file to open from UI, we missed to write genstamp
as hidden parameter. So, when the refresh happens that parameter is missing.

With this patch refresh button is working.
