Subject 0.7.0-beta2 and Hadoop
Date Thu, 14 Oct 2010 00:39:37 GMT
What version of hadoop should i be using with cassandra 0.7.0-beta2?
I am using the latest version 21.0.

Just running a modified version of the WordCount example:
https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/src/

I get a linkage error thrown from the getSplits method.

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext,
but class was expected
