Java Hadoop mapreduce输入路径不存在（MR Job在寻找什么文件系统？）

我正在尝试在Hadoop集群上运行MR作业。有一次我尝试成功，但从昨天开始，我无法运行相同的命令，因为它找不到输入路径

以下是跟踪：

所以当我运行MR作业时，它声称输入路径不存在，但我可以通过

hadoop dfs-ls/…

看到它。Cloudera说，它一直工作到昨天，并没有证据表明集群已经停止运行，集群的健康状况良好。如何解决此问题？

运行作业的命令是

]$ yarn jar /tmp/mihaylov-temp/MR.jar (Main Class Name) (input file path) (output directoru path)

你能检查一下

esb99usr

是否属于

supergroup

group？？？@Mr.Chowdary是的，确实如此。@Mr.Chowdary顺便说一句，文件权限允许任何用户读取hdfs文件，所以我怀疑，这个chmod就是问题所在，你可以试试这个

纱线jar/tmp/mihaylov temp/MR.jar ru.sbt.hadoop.MR.data.index.DayDataIndexStart-Dru.sbt.hadoop.MR.map.mb=3072-Dru.sbt.hadoop.MR.reduce.count=8-Dru.sbt.hadoop.MR.map.count=80/nameservices/supercluster/esbLogs/year/2015/months/7/days/27/hrs/18//nameservices/supercluster/esbLogs/year/2015/months/7/days/27/sort/1440622800966 1440709200966

@Mr.Chowdary不幸的是，这没有帮助
