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]

Need help to understand how to figure out what is the issue and resolve it
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.
