Elliott Clark commented on HBASE-6607:
--------------------------------------
Yep a lot of the Jammon based templates just assume that everything is correctly passed in. So we should either just bail out early with a prettier 500 page if things are still coming up or make it so that the templates can tolerate a null being passed.

[jira] [Commented] (HBASE-6607) NullPointerException when accessing
master web ui while master is initializing
Posted by "Jimmy Xiang (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-6607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13438059#comment-13438059 ]
Jimmy Xiang commented on HBASE-6607:
------------------------------------
That will be great. One more thing is that the server side is better not to throw NPE.
If server side is not fully initialized, it is still better to show something we have so far, so that we can tell from the ui what's going on in the server side.
