With HDFS-16024, we can rename data to the Trash should be based on src
locations. That is great for my useage. After a period of use, I found this
cause a issue.
There are two nameservices ns0 ns1, and ns0 is the default nameservice.
(1) Add moutTable
/home/data -> (ns0, /home/data)
/data1/test1 -> (ns1, /data1/test1 )
/data2/test2 -> (ns1, /data2/test2 )
(2)mv file to trash
ns0: /user/test-user/.Trash/Current/home/data/file1
ns1: /user/test-user/.Trash/Current/data1/test1/file1
(3) client via DFSRouter ls will not see /user/test-user/.Trash/Current/data1
(4) client ls /user/test-user/.Trash/Current/data2/test2 will return exception
.
