-----------------------------------------

             Summary: Inaccurate result displays on presto CLI while select Query after change data type Query
                 Key: CARBONDATA-1695
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1695
             Project: CarbonData
          Issue Type: Bug
          Components: presto-integration
    Affects Versions: 1.3.0
         Environment: spark 2.1
            Reporter: Vandana Yadav
            Priority: Minor
         Attachments: 2000_UniqData.csv

Inaccurate result displays on presto CLI while select Query after change data type Query

Steps to reproduce:
On Beeline:
1) 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");

2) Load Data
LOAD DATA INPATH 'hdfs://localhost:54310/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');

3) Execute Query:
a)desc uniqdata:
outpurt:
+----------------------+-----------------+----------+--+
|       col_name       |    data_type    | comment  |
+----------------------+-----------------+----------+--+
| CUST_ID              | int             | NULL     |
| CUST_NAME            | string          | NULL     |
| ACTIVE_EMUI_VERSION  | string          | NULL     |
| DOB                  | timestamp       | NULL     |
| DOJ                  | timestamp       | NULL     |
| BIGINT_COLUMN1       | bigint          | NULL     |
| BIGINT_COLUMN2       | bigint          | NULL     |
| DECIMAL_COLUMN1      | decimal(30,10)  | NULL     |
| DECIMAL_COLUMN2      | decimal(36,10)  | NULL     |
| Double_COLUMN1       | double          | NULL     |
| Double_COLUMN2       | double          | NULL     |
| INTEGER_COLUMN1      | int             | NULL     |
+----------------------+-----------------+----------+--+

b)alter table uniqdata change decimal_column1 decimal_column1 decimal(36,12);

c)select decimal_column1 from uniqdata;

output:

|      decimal_column1      |

On Presto CLI:
1)Execute Queries:
a) desc uniqdata;

b) select decimal_column1 from uniqdata;

Expected Output: Same as in beeline(no change in value before the decimal.

Actual Output:

    decimal_column1
