Subject [jira] [Commented] (CHUKWA-587) The logic to load the front page of hicc appears to be broken
Date Mon, 13 Jun 2011 11:37:51 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-587?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13048524#comment-13048524

DKN commented on CHUKWA-587:
----------------------------

Thanks for fixing this Eric. I am now able to login to HICC using a remote system (the earlier
jetty fix ) and also load the front page without errors. 

I will create few other defects, so that we have the schemas displayed out of the box correctly.

Cheers, DKN

> We will need to give a consistent behavior for the front page, so that we don't end up
giving an opinion that HICC is not working. There may be a change required in the way, chukwa
hicc loads the front index.jsp by reading the hbase tables.
