我正在尝试使用oozie from hue（cloudera vm）运行一个简单的sqoop导入。提交后的几秒钟，作业就永远挂起了心跳问题，我做了一些搜索，找到了这个线程https://community.cloudera.com/t5/batch-processing-and-workflow/oozie-launcher-never-ends/td-p/13330,我添加了下面所有的yarn-site.xml文件中提到的xml属性，不知道是哪个文件，但是没有用，我仍然面临同样的问题，有人能对此给出一些见解吗？

/etc/hive/conf.cloudera.hive/yarn-site.xml
/etc/hadoop/conf.empty/yarn-site.xml
/etc/hadoop/conf.pseudo/yarn-site.xml
/etc/spark/conf.cloudera.spark_on_yarn/yarn-conf/yarn-site.xml
/etc/hive/conf.cloudera.hive/yarn-site.xml
