Thanks Michael.
A clarification. So the HQL dialect provided by HiveContext, does it use
catalyst optimizer? I though HiveContext is only related to Hive
integration in Spark!
Would be grateful if you could clarify this
cheers

Yeah, the HiveContext is just a SQLContext that is extended with HQL,
access to a metastore, hive UDFs and hive serdes. The query execution
however is identical to a SQLContext.

I generally recommend people use the HQL dialect provided by the
HiveContext when possible:
http://spark.apache.org/docs/latest/sql-programming-guide.html#getting-started
I'll also note that this is distinct from the Hive on Spark project, which
is based on the Hive query optimizer / execution
Hi,
would like to know if there is an update on this?

Hi,

dialect currently.
I would like to know the roadmap for the coming releases.
And, are you focusing more on popularizing the 'Hive on Spark' SQL dialect
or the Spark SQL dialect?
