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.
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"?
Have a look at this file in the source repo https://github.com/apache/cassandra/blob/trunk/bin/cassandratry using "ant artefacts" and look in the build/dist dir.cheersOn 7 Aug 2011, at 03:58, Alvin UW wrote:
I am a beginner.
I checked bin folder under myCassandra. There are only some classes without executable file.
after "ant release", I got the jar file from build folder.
