Receive TimeOutException when try to open two buckets

@simonbasle,
While defining CouchbaseEnvironment we were using queryEnabled(true). We removed this and error also gone now. (couchbase-server-community-3.0.1-centos5.x86_64.rpm is used for couchbase installation)

CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
.connectTimeout(connectionTimeout)
.queryEnabled(true).build();
