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

             Summary: Incorrect output displays on presto CLI after alter table query
                 Key: CARBONDATA-1697
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1697
             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

Incorrect output displays on presto CLI after alter table 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)  alter table uniqdata change decimal_column1 decimal_column1 decimal(36,12);

b) desc uniqdata;

output:
      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(36,12)  | NULL     |
| decimal_column2      | decimal(36,10)  | NULL     |
| double_column1       | double          | NULL     |
| double_column2       | double          | NULL     |
| integer_column1      | int             | NULL     |
+----------------------+-----------------+----------+--+

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

2) Expected Result: it should display the updated precision and scale value of decimal_column1 column as on beeline

3) Actual Result:
      Column        |      Type      | Extra | Comment
---------------------+----------------+-------+---------
 cust_id             | integer        |       |        
 cust_name           | varchar        |       |        
 active_emui_version | varchar        |       |        
 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     | integer        |       |        
(12 rows)
