scala - What is the preferred way to avoid SQL injections in Spark-SQL (on Hive)

Assume a SchemaRDD rdd with a registered table customer. You want to filter out records according to a user input. One idea you might have how to do this is the following:

rdd.sqlContext.sql(s"SELECT * FROM customer WHERE name='$userInput'")

However, since the old days of PHP we know that this can lead to nasty things. Is there an equivalent of PreparedStatement? The only thing I could find that looked remotely relevant is org.apache.commons.lang.StringEscapeUtils.escapeSql.

One option would be to use the thriftserver to expose jdbc, and then the usual techniques could be used (PreparedStatement etc.) to prevent sql injection.
