Hi @smartzjp

hadoop 0.20.x is not supported by es-hadoop. Jackson dependency is just one of the issues (can be resolved by upgrading jackson); the issue is with Hadoop itself which has a completely different contract and some areas that have changed in 1.x.

By the way, the list of supported versions/requirements is under the requirements section in the docs.

Cheers,
