Above topic is very confusing to me. [when using them on Hortonworks sandbox ready made vm]
I am firing all commands on ready made hortonworks sandbox vm.
And unfortunately I am getting just too many errors while starting & stop nfs, portmap services.
I think the vm is not 100% ready to start configuring simple HDFS components.
I am fighting with this vm since last couple of days just for a simple task i.e. create HDFS file system slice of 2gb for testing & mount it on remote system as HDFS.

Amey.
