解决方法：重新配置这个目录

         [hdfs@zte-1 oozie-4.2.0]$ vim conf/oozie-site.xml

错误三：

Oozie重启步骤：

     1.进入/var/local/hadoop/oozie-4.2.0

     2.将Oozie停止运行./bin/oozie-stop.sh

     3.重新进行打包war包 ./bin/oozie-setup.sh prepare-war

     4.重新打开Oozie：./bin/oozie-start.sh

错误四：

错误提示：

 Caused by: java.net.ConnectException: Call From zte-1/192.168.83.128 to zte-1:10020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefuse 

解决方法：根据错误提示，发现是10020端口属于Jobhistory进程，于是启动history进程

$HADOOP_HOME/sbin/mr-jobhistory-daemon.sh start historyserver
