Attempting to use the NFS service to access HDFS following the docs, running into error when trying to set up the NFS service starting the hadoop portmap service:


[root@HW02 hdfs]# hadoop portmap

Not sure how to interpret any of the errors seen here and no other post about this error appear to be on the community site. Any debugging suggestions or solutions for what to do about this?

Should have specified, using Centos7. From the docs "Although NFS Gateway works with portmap included with most Linux distributions, you must use the portmap included in the NFS Gateway package on some Linux systems such as SLES 11 and RHEL 6.2." I took this to mean that I HAD TO run hadoop portmap from the HDP installation (since did not have SLES11 or RHEL6.2). Guess I misread the docs, so I suppose then that I would not stop the rpcbind service (and just ignore the hadoop portmapcommand)?
