Simarpreet Kaur commented on CARBONDATA-1428:
---------------------------------------------
I am not able to reproduce the bug. It is working fine in my system.
No exception in alter drop command and even dropped column is not shown in
describe table command.
> Incorrect Result displays while alter drop command on partitioned and
> non-partitioned table

> Key: CARBONDATA-1428
> URL: https://issues.apache.org/jira/browse/CARBONDATA-1428
> Project: CarbonData
> Issue Type: Bug
> Components: data-query
> Affects Versions: 1.2.0
> Environment: spark 2.1
> Reporter: Vandana Yadav
> Attachments: 2000_UniqData.csv

> Incorrect Result displays while alter drop command on partitioned and
> non-partitioned table
> Steps to reproduce:
> 1) Create a partitioned table
> CREATE TABLE uniqdata_part1 (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) PARTITIONED BY (CUST_ID int) STORED BY 'org.apache.carbondata.format'
> TBLPROPERTIES
> ('PARTITION_TYPE'='RANGE','RANGE_INFO'='9090,9500,9800',"TABLE_BLOCKSIZE"=
> "256 MB")
> 2) Load data into partitioned table
> LOAD DATA INPATH 'hdfs://localhost:54310/uniqdata/2000_UniqData.csv' into
> table uniqdata_part1 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 drop column query on partitioned table
> ALTER TABLE uniqdata_part1 drop columns(BIGINT_COLUMN1)
> 4) Result on beeline
> Error: java.lang.RuntimeException: Alter table drop column operation failed:
> Column bigint_column1 does not exists in the table partition.uniqdata_part1
> (state=,code=0)
> 5) Expected Result:
> it should drop the column from the partitioned table as it is not the
> partitioned column and existing column of the table.
