      Description

      If you try to import a table where any of the rows contain all null values (except for the primary key), the import fails. For example create the following table in Oracle:

      CREATE TABLE employee(id number primary key, test_number number);
      INSERT INTO employee values(1, 123);
      INSERT INTO employee values(2, null);
      COMMIT;

      Then run an import:

      sqoop import --connect jdbc:oracle:thin:@//HOSTNAME/SERVICE --username USERNAME --table EMPLOYEE --password PASSWORD --hbase-table EMPLOYEE --column-family tst --hbase-create-table

      The Import fails with:

      java.lang.IllegalArgumentException: No columns to insert
