Hi,

It is because CarbonData currently is integrated with Spark 1.5/1.6 and CarbonContext is based on HiveContext, so it is based on the Hive parser in HiveContext. But you are right, there is no design limitation about this, Carbon can switch to use ANTLR. I see in Spark 2.0, spark is using ANTLR as well. So maybe it is a good time to switch the parser when doing integration with Spark 2.0.
What is your idea?

Regards,
Jacky
