Subject Re: Flink on AWS EMR Protobuf

I'm not sure if this is a Flink issue. It popped up on other non-Flink 
projects as well:

http://community.cloudera.com/t5/Storage-Random-Access-HDFS/map-red-over-hbase-in-cdh-5-7/td-p/43902

I would defenitely check your dependencies. This looks like conflicting 
versions in your classpaths.
