Hi, Eric and everyone works on chukwa,
Thank you very much! I have install chukwa 0.4.0 successfully! And I
hope the 0.5.0 version could be released as soon as possible~
Thanks for your work on chukwa~ I wish you the best of luck in everything you

Subject: Re: about hicc installation
When releasing Chukwa 0.4, we decided that we don't want to continue to support
loading data from HDFS to MySQL because that approach does not scale well. It
is possible to restore the functionality by copying dbAdmin.sh from Chukwa 0.3
to Chukwa 0.4 to restore mysql functionality. However we do not encourage it.
Try to run dbAdmin.sh as a background process. Then run:
bin/chukwa dp
PostProcessMananger is the process to load data to MySQL.
Hope this works for you.
regards,
Eric
