https://github.com/apache/carbondata/pull/1807 [CARBONDATA-2030]avg with Aggregate table for double data type is failed.
avg with Aggregate table for double data type is failed.
Root Cause:- for avg column , agg table returns sum and count , sum col. data type is based on actual data type of the column but for count col. always LongType .so while doing divide by it is failed in spark layer
Solution :- Change the return datatype for count also . use the same datatype sum column .
