old thread but I ran into a similar problem and wanted to leave the solution I found here.
there is a version incompatibility between pre-2.6 and post-2.6 versions of the com.fasterxml.jackson libraries used by the amazon libs. Talend is likely including both versions of the jackson libraries in your jobs thus causing this failure.
I was able to correct it by entering the exact version of the jackson libs I want in the job or the project pom.
Thanks for sharing your solution here.
