      Description

      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.
