Hi,

I am running some experiments with Parquet and Carbondata. I observe that Carbondata is not recording statistics for Spark to display in Spark UI (history server). I run a projection queries both on Parquet (sqlContext.sql()) and Carbondata (carbonContext.sql()). Parquet is showing the complete details (total tasks and # of disk read in bytes) whereas Carbondata is not showing anything. I would like to have these statistics for carbondata. It helps to see how much Carbondata is reading from the disk which is very useful while comparing it with other formats.

I have also attached screenshot to make it easy to understand. I am using latest Carbondata version apache-carbondata-1.1.0.
