| /** |
| * Test to export sequence file to SQL Server. |
| * |
| * This uses JDBC to export data to an SQLServer database from HDFS. |
| * |
| * Since this requires an SQLServer 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=SQLServerDatatypeExportSequenceFileTest or -Dthirdparty=true. |
| * |
| * You need to put SQL Server JDBC driver library (sqljdbc4.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) and set it's path through -Dsqoop.thirdparty.lib.dir. |
| * |
| * To set up your test environment: |
| * Install SQL Server Express 2012 |
| * Create a database SQOOPTEST |
| * Create a login SQOOPUSER with password PASSWORD and grant all |
| * access for SQOOPTEST to SQOOPUSER. |
| * Set these through -Dsqoop.test.sqlserver.connectstring.host_url, -Dsqoop.test.sqlserver.database and |
| * -Dms.sqlserver.password |
