[jira] [Commented] (HDFS-6630) Unable to fetch the block information by Browsing the file system on Namenode UI through IE9

["Haohui Mai (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-6630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14057065#comment-14057065 ] 

Haohui Mai commented on HDFS-6630:
----------------------------------

The root issue is that the UI should not attempt to make a cross-domain request for {{GET_BLOCK_LOCATIONS}} at all. Therefore the fix should get rid of the cross-domain AJAX call instead of allowing it.

I have attached a simple patch for the above approach.
