Save twitter data streams to Cassandra - cassandra

Question

I am trying to save real time tweets to cassandra, however, Eclipse is showing a marker in this line:
CassandraJavaUtil.javaFunctions(tweets).writerBuilder("Twitter","tweets", CassandraJavaUtil.mapToRow(tweets.class)).saveToCassandra();
Eclipse does not recognize mapToRow() and javaFunctions() even though i've imported all the packages.
I am using the 1.4.0 Cassandra connector in order to be compatible with spark version.
I've seen people using this approach,
javaFunctions(, .class).saveToCassandra("java_api", "sales");
but the documentation tells that it is deprecated with the new versions.
