How to extract data from Hive into IRIS?

Hi guys,

I have a customer trying to extract data from Hive. I've tried to use Data migration to migrate a table into IRIS with JDBC driver. But the migration task always fails as below

Then I tried to create a link table, the task fails too with the following error:

I've tried several ID combinations such as rowkey+userid, userid + datatime, the results are all errors caused by stream property. 

The source table are composed of only Hive string fields.I wonder how may I migrate Hive tables into IRIS. Thanks.
