Accessing HDFS Data with gphdfs (Deprecated)
Note: The external table protocol is deprecated and will be removed in the next major release of Greenplum Database. Consider using the Greenplum Platform Extension Framework (PXF) external table protocol to access data stored in a Hadoop file system.
There are three steps to using the gphdfs protocol with HDFS:
- One-time gphdfs Protocol Installation (Deprecated)
- Specify gphdfs Protocol in an External Table Definition (Deprecated)
