Sqoop version:1.4.6-cdh
Hadoop version:2.6.0-cdh5.8.2
场景:使用Sqoop从MSSqlserver导数据
虽然1.4.6的官网说
Even if Sqoop supports a database internally, you may still need to install the database vendor’s JDBC driver in your
$SQOOP_HOME/lib
path on your client. Sqoop can load classes from any jars in$SQOOP_HOME/lib
on the client and will use them as part of any MapReduce jobs it runs; unlike older versions, you no longer need to install JDBC jars in the Hadoop library path on your servers.
我已经把sqljdbc4.jar放到了$SQOOP_HOME/lib下面,但是仍然会报出错误
ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not load db driver class: com.microsoft.sqlserver.jdbc.SQLServerDriver java.lang.RuntimeException: Could not load db driver class: com.microsoft.sqlserver.jdbc.SQLServerDriver
尝试着放到 $HADOOP_HOME/lib 下面,仍然不起作用;
最后放到 $HADOOP_HOME/share/hadoop/common/lib 下面OK了。
