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 tried working with standalone java and it works fine, but throws error in my project. It throws exception at the following line :

this.cluster = Cluster.builder().addContactPoint(node).withPort(port).build();

Appreciate your guidance.

Answer 1

There must be a version of Guava in your classpath that is older than 16.0.1. The java driver only supports Guava 16.0.1 through 19 (3.2.0 which will be released soon will support 16.0.1 through 21).

Check your classpath for an older version of guava and replace it with a version between 16.0.1 and 19.0. It is also possible that your application has multiple guava jars in your classpath, in which case you should remove the older one(s).
