The logic to load the front page of hicc appears to be broken
-------------------------------------------------------------

                 Key: CHUKWA-587
                 URL: https://issues.apache.org/jira/browse/CHUKWA-587
             Project: Chukwa
          Issue Type: Bug
          Components: User Interface
    Affects Versions: 0.5.0
         Environment: A stand alone server with all components
            Reporter: DKN
             Fix For: 0.5.0


I get the following error, in spite of running hicc, collector, agents etc continuously for
more than 5 days.

This appears only when I access : http://localhost:4080/hicc URL. Note that the URL : http://localhost:4080/hicc/jsp/graph_explorer.jsp
appears to work okay for me. 

HTTP ERROR: 500

INTERNAL_SERVER_ERROR

RequestURI=/hicc/

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.
