Hbase import fails if there is a row where all columns are null

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:
