Guava incompatibility issues

Hello,

We installed Cloudera CDH5, Cassandra DataStax Community Distribution v3.3, now we run this sample-KafkaSparkCassandra on top of them, can getting such error:

Caused by: java.lang.IllegalStateException: Detected Guava issue #1635 which indicates that a version of Guava less than 16.01 is in use. This introduces codec resolution issues and potentially other incompatibility issues in the driver. Please upgrade to Guava 16.01 or later.

I wonder should I manually change Guava to 16.01 or later?

thanks
