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
