Exception in thread "main" java.io.IOException: The ownership on the staging directory /tmp/hadoop-yarn/staging/hadoop/.staging is not as expected. It is owned by Administrators. The directory must be owned by the submitter hadoop or by hadoop
这里可以改一下Administrators为hadoop，如果注销重启后并不能生效就把tmp/hadoop-yarn/staging/hadoop/.staging整个目录删了，当然如果你的并不是Administrator这时候就把你对应的用户名改成hadoop.此处的hadoop就是你的集群名称
重新运行程序若出现
job.splitmetainfo does not exist
不必惊慌在你的程序中添加 conf.set("fs.default.name", "hdfs://192.168.199.132:9000");改成自己的ip地址就解决了
