I am using Spark 1.3.0 and Spark Avro 1.0.0. I am working from the example on the repository page.

This following code works well:

val df ="src/test/resources/episodes.avro")
df.filter("doctor > 5").write.avro("/tmp/output")

But what if I needed to see if the doctor string contains a substring?

You can use contains (this works with an arbitrary sequence):

Note: do import:  import sqlContext.implicits._


like (SQL like with SQL simple regular expression with _ matching an arbitrary character and % matching an arbitrary sequence):


or rlike (like with Java regular expressions):


depending on your requirements. LIKE and RLIKE should work with SQL expressions as well.
