Subject Running Giraph 1.0.0 for Hadoop 2.0.0
Date Tue, 01 Apr 2014 12:49:29 GMT
Hi All,

I built Giraph 1.0.0 jar for Hadoop 2.0.0. When I tried to run the giraph
job, I got following errors-

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

Am I missing something or doing something wrong? How can I resolve this
issue? Please help.
