SKD3.0 Situational running Memcached tests getting "Received error status from GlobalLoader"

when running a memd test, sdkd-java (alpha 6 or alpha 7-SNAPSHOT) always fails with "Received error status from GlobalLoader: CarrierGlobalConfigResponse{status=NOT_FOUND, content=}"

Seen on Jenkins (alpha 6): http://sdkbuilds.sc.couchbase.com/view/JAVA/job/server-build-test-java/job/centos-java-sdk-server-situational-tests/711/console
