+1 I had to browse spark-catalyst sources to find what is supported: https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/SqlParser.scala

I'm struggling trying to combine selects, groupBy and aggregations. A language definition would also help. I perused these resources, but still have some gaps in my understanding and things are not doing what I'd expect: https://spark.apache.org/docs/1.3.0/sql-programming-guide.html https://spark.apache.org/docs/1.3.0/api/scala/index.html#org.apache.spark.sql.DataFrame https://spark.apache.org/docs/1.3.0/api/scala/index.html#org.apache.spark.sql.functions$ Thanks, Gerard.
