Akira AJISAKA commented on HDFS-6654:
-------------------------------------
bq. Step 4: Now unable to write a File to Dir1 from User2
This is by specification. User2 needs EXECUTE permission to write a file to
Dir1.
bq. Fetching filesystem name , when one of the disk configured for NN dir
becomes full returns a value "null".
I suppose it has been fixed by HADOOP-10462. You will see the right value in
the next release.

> Step 1: Created a Dir1 with User1

> Step 2: Changed the permission (600) for Dir1 recursively
> ./hdfs dfs -chmod -R 600 /Dir1
> Step 3: setfacls is executed to give read and write permissions to User2
> which belongs to the same group as User1
> ./hdfs dfs -setfacl -R -m user:User2:rw- /Dir1
> ./hdfs dfs -getfacl -R /Dir1
> No GC_PROFILE is given. Defaults to medium.
