> Incorrect result displays after creating data map
> Steps to Reproduce:
> 1. Create a TAble:
> CREATE TABLE uniqdata(CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES('DICTIONARY_INCLUDE'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')
> 2. Load Data
> a) LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',', 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')
> b) LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',', 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')
> c) LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',', 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')
> Execute Query:
> a) select avg(cust_id) from uniqdata group by cust_id
> output: 
> | 9460.0 |
> | 9671.0 |
> | 10403.0 |
> | 10725.0 |
> | 10867.0 |
> +---------------+--+
> | avg(cust_id) |
> +---------------+--+
> | 9067.0 |
> | 9901.0 |
> +---------------+--+
> 2,002 rows selected (1.718 seconds)
> b) create data map:
> create datamap uniqdata_agg on table uniqdata using 'preaggregate' as select avg(cust_id) from uniqdata group by cust_id;
> c) select avg(cust_id) from uniqdata group by cust_id;
> output:
> | NULL |
> | NULL |
> | NULL |
> +---------------+--+
> | avg(cust_id) |
> +---------------+--+
> | NULL |
> | NULL |
> +---------------+--+
> 2,002 rows selected (0.895 seconds)
> Expected result: it should display similar result as before creating datamap.
