I am evaluating Ignite and trying to load CSV data to Apache Ignite. I have created a table in Ignite:

jdbc:ignite:thin://127.0.0.1/> create table if not exists SAMPLE_DATA_PK(SID varchar(30),id_status varchar(50), active varchar, count_opening int,count_updated int,ID_caller varchar(50),opened_time varchar(50),created_at varchar(50),type_contact varchar, location varchar,support_incharge varchar,pk varchar(10) primary key);

I tried to load data to this table with command:

copy from '/home/kkn/data/sample_data_pk.csv' into SAMPLE_DATA_PK(SID,ID_status,active,count_opening,count_updated,ID_caller,opened_time,created_at,type_contact,location,support_incharge,pk) format csv;

But the data load is failing with this error:

Error: Server error: class org.apache.ignite.internal.processors.query.IgniteSQLException: Value conversion failed [column=COUNT_OPENING, from=java.lang.String, to=java.lang.Integer] (state=50000,code=1)
java.sql.SQLException: Server error: class org.apache.ignite.internal.processors.query.IgniteSQLException: Value conversion failed [column=COUNT_OPENING, from=java.lang.String, to=java.lang.Integer]

You have to upload CSV without header line. Which contains the column names. An error is thrown when trying to convert the string value "count_opening" to a Integer.
