Re: hicc start problem:"Unable to load dashboard"

Hi  Eric,

Thanks for your reply, now the web interface work fine ( also for my usage,
i monitor other logs, not only Hadoop cluster)

Then, i came to store the data into HDFS, and run Demux and PostPocessor to
divide the logs into datatype/datetime categories,
Here i found some running exceptions as belows: it says jdbc.conf is not
found.
Does it mean in Demux and PostProcess, the results will be written into
databases?  can you give some hints on what will be written for any reasons?
Thanks~
Best Regards!
Scott
*Error logs sends to the console , not in Demux, postProcessor log file*
