Building Apache Pig for Hadoop 2.4 version

I downloaded PIG 0.14 and did an ant -dhadoopversion=23 jar , but when I used it on Hadoop 2.4 its not working. Is there anything I should do other than just running ant?

Pig is running, but showing errors

ang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected

thanks !

If you checked out Pig from SVN trunk you can verify the Hadoop version it uses at $PIG_HOME/ivy/libraries.properties . For the "23" profile it is 2.4.0 . After you have built Pig from source ( ant -Dhadoopversion=23 ) you can verify whether ivy has retrieved the correct Hadoop jars under $PIG_HOME/build/ivy/lib/Pig .

I suspect that you have a wrong Hadoop version in your PIG_CLASSPATH.
