[Hadoop] java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected


(Shaun Campbell) #1

Hi there,

I'm having a bit of trouble using the Maven published version of
elasticsearch-hadoop 1.3.0M3. According to the docs, it should be
compatible with both Hadoop 1.x and 2.x, although I'm seeing an error
indicating otherwise. I downloaded the sources, and modified the build to
compile against hadoop 2.x only and this seems to have worked. Is there a
java option perhaps that I should add to make the maven distributed jar
work correctly?

Hi,

You bumped into a bug that slipped in M3. This has been fixed in master - can you please try out the SNAPSHOTs [1]?

Thanks,

Excellent. The fix will be part of RC1 which is not too far off.

Cheers,
