Thanks guys. The problem is solved. I copied cassandra and cassandra.in to my bin folder. Then used "ant release " to generate my customized cassandra.jar in dist folder. it worked.
To Aaron: I tried "ant artefacts", but it failed. is it because I am using Cassandra 0.7? What's the difference between "ant artefacts" and "ant release"? 2011/8/6 aaron morton <aa...@thelastpickle.com> > Have a look at this file in the source repo > https://github.com/apache/cassandra/blob/trunk/bin/cassandra > > try using "ant artefacts" and look in the build/dist dir. > > cheers > > ----------------- > Aaron Morton > Freelance Cassandra Developer > @aaronmorton > http://www.thelastpickle.com > > On 7 Aug 2011, at 03:58, Alvin UW wrote: > > > Thanks. > > I am a beginner. > I checked bin folder under myCassandra.
