Re: extending demux
Eric, Thanks for summarizing it here. I am able to now create successfully my
parsers and see that up in HICC (using the trunk .. ) I had to find my own
ways of a development methodology though .. using eclipse.
A few questions :

Having to extend demux with our custom parsers appear really promising and
opens up a lot of opportunities. We will need to see how best we can make
this framework "customizable" for custom defined data types.
Many thanks .. DKN

Hi DKN,
Chukwa ant build system could use some improvements and features like mvn eclipse:eclipse to generate project file for eclipse. I filed https://issues.apache.org/jira/browse/CHUKWA-590 to tackle this issue. For building software on top of Chukwa, it would be nice to add "power by Chukwa" to advertise and attract more developers. Thanks for the feedbacks. :)
Regards,
Eric
