I tried to create a table with the following command:
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")
and when I tried to add a new column to this table by using:
alter table uniqdata add columns(newcol5 int) tblproperties('default.value.nCol'='123456789');
It does not throw any error and the query was passed successfully. The above alter command should throw an exception as the new column name to be added does not matches with the column name in the default value property.
