-------------------------------------
I am working for this issue
> Insert query not working with UNION
> -----------------------------------
>
> Key: CARBONDATA-617
> URL: https://issues.apache.org/jira/browse/CARBONDATA-617
> Project: CarbonData
> Issue Type: Bug
> Components: data-query
> Affects Versions: 1.0.0-incubating
> Environment: Spark 1.6
> Hadoop 2.6
> Reporter: Deepti Bhardwaj
> Assignee: QiangCai
> Priority: Minor
> Attachments: 2000_UniqData.csv,
> thrift-error-log-during-insert-with-union
>
>
> I created 3 table all having same schema
> Create table commands:
> 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';
> CREATE TABLE student (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';
> CREATE TABLE department (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';
> and I loaded the uniqdata and department table with the attached
> CSV(2000_UniqData.csv)
> and the insert query used to load data in student table was:
> insert into student select
> CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1
> from uniqdata UNION select
> CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1
> from department;
> When I try to insert data into student with union operation, it gives
> java.lang.Exception: DataLoad failure.(attached below)
> The Union query works well when used alone but when insert is used with Union
> it fails.
> Also, if I used hive tables instead of carbon tables insert does not work.
