Arpit Agarwal commented on HADOOP-11004:
----------------------------------------
This Jira brings up two separate issues:
# Accessing HDFS files via NFS does not respect existing ACLs. If so this needs
to be fixed since we'd expect file access via NFS to respect both HDFS
unix-style permissions and ACLs.
# HDFS ACLs are not exposed when listing files/directories via NFS. HDFS-6949
as [~brandonli] mentioned.
> NFS gateway doesn't respect HDFS extended ACLs
> ----------------------------------------------

> Key: HADOOP-11004
> URL: https://issues.apache.org/jira/browse/HADOOP-11004
> Project: Hadoop Common
> Issue Type: Bug
> Components: nfs, security
> Affects Versions: 2.4.0
> Environment: HDP 2.1
> Reporter: Hari Sekhon
>
> I'm aware that the NFS gateway to HDFS doesn't work with secondary groups
> until Hadoop 2.5 (HADOOP-10701) but I've also found that when setting
> extended ACLs to allow the primary group of my regular user account I'm still
> unable to access that directory in HDFS via the NFS gateway's mount point,
> although I can via hadoop fs commands, indicating the NFS gateway isn't
> respecting with HDFS extended ACLs. Nor do the existence of extended ACLS
> show up via a plus sign after the rwx bits in the NFS directory listing as
> they do in hadoop fs listing or as regular Linux extended ACLs both do.
