[root@spark2 client]# cat /var/log/sqoop2/localhost.2017-12-22.log
十二月 22, 2017 10:29:17 上午 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet v1.JobServlet threw exception
解决办法是 在sqoop 所在服务器上执行入下操作:
cd /opt/cloudera/parcels/CDH/lib/hadoop/client
sudo ln -s ../../hadoop-hdfs/lib/jackson-mapper-asl-1.8.8.jar
sudo ln -s ../../hadoop-hdfs/lib/jackson-core-asl-1.8.8.jar

CM的SQOOP2组件需要重启。
