Hadoop Foreign Data Wrapper Guide

The Hadoop Foreign Data Wrapper (hdfs_fdw) is a Postgres extension that allows you to access data that resides on a Hadoop file system from EDB Postgres Advanced Server. The foreign data wrapper makes the Hadoop file system a read-only data source that you can use with Postgres functions and utilities, or in conjunction with other data that resides on a Postgres host.

The Hadoop Foreign Data Wrapper can be installed with an RPM package. You can download an installer from the EDB website.

This guide uses the term Postgres to refer to an instance of EDB Postgres Advanced Server.
