Configuring An NFS Gateway on BDA and Client Setup to Access NFS Gateway (Doc ID 1998215.1)

Last updated on OCTOBER 11, 2016

Applies to:

Big Data Appliance Integrated Software - Version 3.0 and later
Linux x86-64

Purpose

This document provides details about configuring NFS Gateway Role on Oracle Big Data Appliance and how to setup Clients to access the NFS Gateway.

The NFS Gateway role implements an NFSv3 gateway. It is an optional role for a CDH 5 HDFS service.

The NFSv3 gateway allows a client to mount HDFS as part of the client's local file system. The gateway machine can be any host in the cluster, including the NameNode, a DataNode, or any HDFS client. The client can be any NFSv3-client-compatible machine.

After mounting HDFS to his or her local filesystem, a user can:
  • Browse the HDFS file system as though it were part of the local file system
  • Upload and download files from the HDFS file system to and from the local file system.
  • Stream data directly to HDFS through the mount point.
File append is supported, but random write is not.
  For detailed instructions about requirements, adding and configuring an NFS Gateway, please refer to Cloudera documentation.
