我正在尝试在两个Mapr群集之间复制文件
hadoop distcp maprfs:///path/to/source/hive/table maprfs:///path/to/destination/hive/table
源表中有一些数据，但目标表中没有数据。我刚刚在目的地使用了create table命令。
但是对于上面的distcp命令，我得到了
java.io.FileNotFoundException: Requested file maprfs:/var/mapr/cluster/yarn/rm/staging/some_user/.staging/job_1528383939830_608130 does not exist.

此登台文件是什么，我如何获取它？我的语法正确吗？
