Upon further debugging of this issue, it appears that the Cassandra server does not start hence the NoHostAvailableException is thrown at com.datastax.driver.core.ControlConnection.reconnectInternal(ControlConnection.java:233)

The below error is seen on additional debug statements

Connection exception
 Errors = {localhost/0:0:0:0:0:0:0:1:9239=com.datastax.driver.core.exceptions.TransportException: [localhost/0:0:0:0:0:0:0:1] Cannot connect}

On debugging the dependent projects that Apache Cassandra interpreter uses, the dependency Achilles has a dependency on Cassandra 2.2.3. Cassandra 2.2.3 has a dependency on JNA version 4.0.0 which is not compatible with Power.

The errors are resolved when the JNA version 4.2.0 is used as this version has support for ppc64le.

On checking out the latest version of Zappline 0.7, I am still getting the above test case failures on s390x systems.
