Subject Re: hicc start problem:"Unable to load dashboard"
Date Fri, 15 Jun 2012 03:33:47 GMT
Hi Scott,

Demux with HDFS and PostProcessor store data to mysql.  This is the
old design before HBase came into existence.  The idea was to cleanse
the data and extract metrics to store in database for hicc to query.
PostProcessor was legacy code and it should not be used.

regards,
Eric
