> Incorrect result displays after applying drop column query on a table
> ---------------------------------------------------------------------
>
> Key: CARBONDATA-1675
> URL: https://issues.apache.org/jira/browse/CARBONDATA-1675
> Project: CarbonData
> Issue Type: Bug
> Components: presto-integration
> Affects Versions: 1.3.0
> Environment: spark 2.1
> Reporter: Vandana Yadav
> Assignee: anubhav tarar
> Priority: Minor
>
> Incorrect result displays after applying drop column query on a table
> Steps to reproduce:
> 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:
> 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(30,10) | NULL |
> | DECIMAL_COLUMN2 | decimal(36,10) | NULL |
> | Double_COLUMN1 | double | NULL |
> | Double_COLUMN2 | double | NULL |
> | INTEGER_COLUMN1 | int | NULL |
> +----------------------+-----------------+----------+--+
> 12 rows selected (0.041 seconds)
>
> Start Presto server
> sudo ./bin/launcher run
> run presto CLI:
> ./presto --server localhost:9000 --catalog carbondata --schema newpresto
> On Presto CLI:
> 1) Execute Query:
> a) desc uniqdata;
> output:
> 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)
> b) Now on Beeline execute the drop column query on the table which is :
> alter table uniqdata drop columns (CUST_ID)
> c)desc uniqdata;
> Expected output: it should display updated table description as on beeline
> Actual output:
> on beeline:
> 0: jdbc:hive2://localhost:10000> desc uniqdata;
> +----------------------+-----------------+----------+--+
> | col_name | data_type | comment |

> | active_emui_version | string | NULL |
> | dob | timestamp | NULL |
