David Robson created SQOOP-862:
----------------------------------
Summary: Hbase import fails if there is a row where all columns
are null
Key: SQOOP-862
URL: https://issues.apache.org/jira/browse/SQOOP-862
Project: Sqoop
Issue Type: Bug
Reporter: David Robson
Assignee: David Robson
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:
