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.
