> 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)
