Avro looking for SnappyCodec is throwing NoClassDefFoundError

I have looked all over the web and found this is a pretty common error, but no solution has helped me.

I am reading from a kafka topic. Up until now I haven't had an issue doing so, but now I am getting this error when I run on the flink cluster up in the aws environment, but not in my IDE (intellij):

From what I can find online it sounds like the usual reason has to do with different version being compiled than what is expected, to put it simply. But I am just at a loss. Here is the pom.xml as well:

I am sure it isn't that hard of a thing, but I really have just hit the point where you end up doing more harm than good trying one thing after another.

Thanks for any help in advance!

EDIT:

Also should add that I can find Snappy.java in my IDE at that path (org.xerial.snappy.Snappy).

Solution

  • Upon talking with a contact at data artisans (creators of Flink), it turns out there is a bug with 1.3 that is the reason for this. Here is the link to the bug report https://issues.apache.org/jira/browse/FLINK-6965.
