I am having problems starting the NFS server and mounting NFS. Not sure if the license or something else is a problem! I have a community edition (M3) license, with the following license information:

# maprcli license list

grace  id                       description   deletable  license                                                                                                                                                                                                                                                                                                                                                                                                   maxnodes
true   xxxxxxxxxxxxxxxxxxx=  MapR Base Edition  false version: "4.0"

customerid: "BaseLicenseUser"

issuer: "MapR Technologies, Inc."

licType: Base

description: "MapR Base Edition"

enforcement: HARD

capabilities {

  feature: MAXNODES

  name: "Max Nodes in Cluster"

  permission: ALLOW

  featureData {

maxNodes: "unlimited"



capabilities {

  feature: MAPR_TABLES

  name: "MapR Tables"

  permission: ALLOW



Following are the roles installed:

# service rpcbind status

I have also tried to restart the warden

# service mapr-warden restart


With no difference !
