dbcompile-cassandra-0.7 errors

[mangobatao]

I use the latest version of YCSB to connect to the cassandra (0.7.10) with ant 1.8.2 and jdk 1.6, but get some errors:

I see other people have the same problems, could someone tell me how could I solve this kind of problem?

Hi mangobatao,

Can you copy and paste the output of "ant -v dbcompile-cassandra-0.7"? I'm suspecting ant might be picking up a wrong version of cassandra jar file.

Thanks!

I have just solved this problem as the commit "Updated Cassandra0.7 plugin to use API for 0.7 release: replaced byte[]". Thanks a lot.
