| /** |
| * Test the DB2Manager implementation. |
| * |
| * This uses JDBC to import data from an DB2 database into HDFS. |
| * |
| * Since this requires an DB2 Server installation, |
| * this class is named in such a way that Sqoop's default QA process does |
| * not run it. You need to run this manually with |
| * -Dtestcase=DB2ManagerImportManualTest |
| * |
| * You need to put DB2 JDBC driver library (db2jcc4.jar) in a location |
| * where Sqoop will be able to access it (since this library cannot be checked |
| * into Apache's tree for licensing reasons). |
| * |
| * To set up your test environment: |
| * Install DB2 Express 9.7 C server. |
| * Create a database SQOOP |
| * Create a login SQOOP with password PASSWORD and grant all |
| * access for database SQOOP to user SQOOP. |
