/**
 * Test multiple columns in SQL Server.
 *
 * This uses JDBC to import data from an SQLServer database to 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=SQLServerMultiColsTest 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
