Ted Yu updated SPARK-10561:
---------------------------
Description:
Here is the discussion thread:
http://search-hadoop.com/m/q3RTtcD20F1o62xE
Richard Hillegas made the following suggestion:
A machine-generated BNF, however, is easy to imagine. But perhaps not so easy
to implement. Spark's SQL grammar is implemented in Scala, extending the DSL
support provided by the Scala language. I am new to programming in Scala, so I
don't know whether the Scala ecosystem provides any good tools for
reverse-engineering a BNF from a class which extends
scala.util.parsing.combinator.syntactical.StandardTokenParsers.
