Íñigo Goiri commented on HDFS-14210:
------------------------------------
Correct, my main concern is doing unnecessary RPC calls.
Another concern is having a misbehaving subcluster which may delay all the
requests because of this.
The other issues is that now we need to process the result of
{{invokeConcurrent()}} and check where it succeeded and where it did not.

Problems with this approach what I am feeling is actually if we set on say one
and not on others then that is a bit of inconsistancy since for the end user
that mount is just a mere directory and he is unaware about that there is a
layer of router in between. And if I see someway it feels like half directory
is say erasure coded and half is not. Doesn't sound much logical to me.

The main issue that this discussion brings up is that we should distinguish
files and directories.
Setting EC to a folder should happen in all folders and provide a consistent
view across subclusters.
We need to manage temporary unavailable subclusters though.
Anyway, my proposal is to split {{MountTable#isPathAll()}} into
{{MountTable#isDirectoryAll()}} and {{MountTable#isFileAll()}}.
Based on this we can setup the parameters using one approach or the other.

> 1) A mount point with multiple destinations.
> 2) ./bin/hdfs dfs -setfacl -m user:abc:rwx /testacl
> 3) where /testacl => /test1, /test2
> 4) command works for only one destination.
> ACL should be set on both of the destinations.
