Premchandra Preetham Kukillaya commented on HADOOP-10701:
---------------------------------------------------------
@Harsh, Thanks for comming up with Fix . But here are my questions
1) As per the fix you are using the List of GID's sent by NFS Client to NFS
Proxy. But in this approach are disadvantages like 1) max of 16 GID/ UNIX ID
2) Requires integration of Client machine with LDAP and its a big pain.
2) Why the List of GID for each UID is not retrieved from OS/LDAP instead of
list of List of GID's sent by NFS Client to NFS Proxy. Doing so it will
eliminate the need for Client machines to integrate with LDAP.
> The bug is while accessing NFS Mounted File System the permission is always
> validated based on the primary Unix group the user is associated with and
> Secondary Unix groups are ignored.
