Íñigo Goiri commented on HDFS-14431:
------------------------------------
In the particular you mentioned before like:
* /mntsrc in ns1 and ns2
* /mntdst in ns2 and ns3
If we are renaming a file that is originally in ns1, we will fail
(RenameNotAllowedException), but if the file is originally in ns2, we can do
the rename, right?
Then if the file already exists in ns3, then we fail for the src being in ns1
but delete it from ns3 for the file being in ns2.
Does it sound right?
