Hi Till, Thanks for the response. I’m hoping not to have to change Flink’s lib folder. The path I specified does exist on each node, and –C is supposed to add the path to the classpath on all nodes in the cluster. I might try to bundle the snappy jar within my job jar to see if that works.

When specifying the classpath manually you have to make sure that all distributed components are also started with this classpath.

I’ve also tried adding the native dir to the classpath. Neither have helped. -C file://usr/hdp/current/hadoop-client/lib/snappy-java-1.0.4.1.jar -C file://usr/hdp/current/hadoop/lib/native/ Any thoughts on how I can get this to work?
