    Error: Found interface org.apache.hadoop.mapreduce.TaskAttemptContext, but class was expected

    I have jar for map reduce, which works fine with cloudera hadoop 0.20.2, I want to upgrade it to hdp 2.x. I had set up hadoop and map reduce and ran the smoke test, everything works fine, also tested with wordcount program from the scratch.

    It gets successfully compiled, and packaging the jar.

    My maven dependency:tree -Dverbose – shows only Hadoop 2.x related jars….

    Thanks in advance..
