> Incorrect result displays to user in presto integration as compare to CarbonData (As in Carbondata our result set include null values but in presto it exclude those).
> Steps to reproduce :
> 1. In CarbonData:
> a) Create 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 ("TABLE_BLOCKSIZE"= "256 MB");
> b) Load data :
> LOAD DATA INPATH 'hdfs://localhost:54310/2000_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');
> 2. In presto
> a) Execute the query:
> select CUST_NAME from uniqdata where CUST_NAME !='CUST_NAME_01844' order by CUST_NAME
> expected result : it should display all cust_name except "cust_name_01844"
> Actual result:
> In CarbonData:
> "| CUST_NAME_01995 |
> | CUST_NAME_01996 |
> | CUST_NAME_01997 |
> | CUST_NAME_01998 |
> | CUST_NAME_01999 |
> +------------------+--+
> 2,012 rows selected (1.777 seconds)

> In presto:
> "CUST_NAME_01997
> CUST_NAME_01998
> CUST_NAME_01999
> (2000 rows)
