>
> In cloud deployment, client machines and Hadoop Cluster are sometimes in
> different DMZ and LDAP in some other. Integration client machines with LDAP
> might require lot of firewall tickets, which can be a pain especially when
> users keep on adding new client machines.
> When the client is not integrated with LDAP for the group mapping, NFS should
> not use the group list in the request. Instead, NFS gateway can get the group
> list from local name service.
> This JIRA is to track the effort to provide a configuration option to get
> list of GID from LDAP/OS for making the deployment at Cloud easier. Also this
> can remove the limitation of 15 GID in the NFS request.
