Cannot change HDFS ACLs

[#1]

Hi guys,

I was playind around with ACLs on a test cluster and set them recursively on /user to others::r-- instead of others::r-x. Then I wanted to change it back on /user/hive/warehouse but no matter what I do I cannot change them:

hdfs dfs -getfacl /user/hive/warehouse
# file: /user/hive/warehouse
# owner: hive
# group: hive
user::rwx
user:hive:rwx
group::---
group:hive:rwx
mask::rwx
other::--x

hdfs dfs -setfacl -m group::rwx /user/hive/warehouse

hdfs dfs -getfacl /user/hive/warehouse
# file: /user/hive/warehouse
# owner: hive
# group: hive
user::rwx
user:hive:rwx
group::---
group:hive:rwx
mask::rwx
other::--x

It always remains the same, I cannot change anything at all... Any ideas?

Take a look at some of the reasons for such a behaviour, noted in this thread: http://community.cloudera.com/t5/Storage-Random-Access-HDFS/HDFS-Cannot-change-permissions-of-a-sing...?

Thanks! I've totally forgotten about the existence of Sentry 😕
