Hi Steve,
we had a similar problem. We've compiled our code with version 0.21
but included the wrong jars into the classpath. (version 0.20.2;
NInputFormat.java). It seems that Hadoop changed this class to an
interface, maybe you've a simliar problem.
Hope this helps.
Sebastian
Zitat von Steve Lewis <lordjoe2...@gmail.com>:
Cassandra sees this error with 0.21 of hadoop
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found
interface org.apache.hadoop.mapreduce.JobContext, but class was expected
I see something similar
Error: Found interface org.apache.hadoop.mapreduce.TaskInputOutputContext,
but class was expected
I find this especially puzzling
since org.apache.hadoop.mapreduce.TaskInputOutputContext IS a class not an
interface
Does anyone have bright ideas???
