Hi Liuhang, You will need to have MySQL Connector/J jar file put into CHUKWA_HOME/lib directory, and configure chukwa-env.sh to have:
TODO_CHUKWA_JDBC_DRIVER=com.mysql.jdbc.Driver TODO_CHUKWA_JDBC_URL_PREFIX=jdbc:mysql:// both properties configured. In addition, also specify jdbc.conf to have cluster name maps to mysql url. For example, demo=jdbc:mysql://localhost:3306/test?user=root Detail instruction is also on Chukwa 0.4 document: http://incubator.apache.org/chukwa/docs/r0.4.0/admin.html#Set+Up+the+Database regards, Eric On Sun, Dec 11, 2011 at 10:13 PM, zhangliuhang <[email protected]> wrote: > Hi, Eric, > Thanks for your help, I have set up hicc successfully, but I encounter > another problem that my database seemed to be nothing, > The hicc show me "no data available", I don't know how to download data from > the hdfs to mysql, could you help me ? > > Liuhang Zhang > > -----Original Message----- > From: chukwa-user-return-1042-zhangliuhang=ict.ac...@incubator.apache.org > [mailto:chukwa-user-return-1042-zhangliuhang=ict.ac...@incubator.apache.org] > On Behalf Of Eric Yang > Sent: 2011年12月12日 13:10 > To: [email protected] > Subject: Re: about hicc installation > > For HICC, just run it as ./bin/chukwa hicc.
