Verify validity of the NFS services

After starting the NFS services on the Gateway, you must verify whether all the services are running. Additionally, you must ensure that the HDFS namespace is exported and can be mounted.

1. Run the rpcinfo command to verify whether all the NFS services are running.
   rpcinfo -p $nfs_server_ip

   The command returns an output similar to the following:

       program vers proto   port
       100005    1   tcp   4242  mountd
       100005    2   udp   4242  mountd
       100005    2   tcp   4242  mountd
       100000    2   tcp    111  portmapper
       100000    2   udp    111  portmapper
       100005    3   udp   4242  mountd
       100005    1   udp   4242  mountd
       100003    3   tcp   2049  nfs
       100005    3   tcp   4242  mountd

2. Verify that the HDFS namespace is exported and can be mounted.
   showmount -e $nfs_server_ip

   The command returns an exports list similar to the following:

   Exports list on $nfs_server_ip : / (everyone)
