1.Setting Extended ACL recursively for a user belonging to the same group is
not working
{noformat}
Step 1: Created a Dir1 with User1
./hdfs dfs -rm -R /Dir1
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.
# file: /Dir1
# owner: User1
# group: supergroup
user::rw-
user:User2:rw-
group::---
mask::rw-
other::---
Step 4: Now unable to write a File to Dir1 from User2
./hdfs dfs -put hadoop /Dir1/1
No GC_PROFILE is given. Defaults to medium.
put: Permission denied: user=User2, access=EXECUTE,
inode="/Dir1":User1:supergroup:drw------

2. Fetching filesystem name , when one of the disk configured for NN dir
becomes full returns a value "null".
