I think that you have conflicting versions of Jackson on your classpath (the dreaded JAR hell). Please ensure that you have the versions of Jackson that Elasticsearch depends on, and that you don't have any conflicting versions.

Man that escalated quickly 😃  
I also had multiple versions of jackson. Removing older version helped.
