 网上说是MySQL驱动包的问题下，需要更换驱动包：“原有的jar包是mysql-connector-java-5.1.17.jar，替换成mysql-connector-java-5.1.32-bin.jar，可以使用了”  ------亲测不行

cd /opt/cloudera/parcels/CDH-5.10.0-1.cdh5.10.0.p0.41/lib/sqoop/lib/
ll
cp /home/zc.lee/mysql-connector-java-5.1.32-bin.jar ./mysql-connector-java.jar

运行起来还是没有能把mr task跑起来，报错和上次一致。
