Hi, We can use ANTLR with Spark1.5/1.6. There is no compatibility issue. We can replace the carbon parser with the ANTLR even when CarbonData is integrated with Spark 1.5/1.6. And when we are integrating with Spark 2.0, not much changes will be required in the ANTLR parser.
But, if integration with Spark 2.0 is planned in near future, we can switch to ANTLR parser at that time as well.
