-----------------------------------------
Summary: 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
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 |

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 |
+----------------------+-----------------+----------+--+
| 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 |
+----------------------+-----------------+----------+--+
11 rows selected (0.039 seconds)
On presto CLI
presto:newpresto> desc uniqdata;
Column | Type | Extra | Comment
