You can define the following objects in an HDFS mapping:

A flat file data object or a complex file data object read operation as the input to read data from HDFS
Transformations
A flat file data object or a complex file data object write operation as the output to write data to HDFS

If you use a complex file data object as a source, you must use a Data Processor transformation to parse the file. Similarly, when you use a complex file data object as a target, you must use a Data Processor transformation to convert the source data into a binary format. You can then use the binary stream to write data to the complex file.

You can use complex file sources and targets as dynamic sources and targets in a mapping. For information about dynamic mappings, see the

Informatica Developer Mapping Guide

.

Validate and run the mapping. You can deploy the mapping and run it or add the mapping to a Mapping task in a workflow and run the workflow. You can also run the mapping in a Hadoop run-time environment.
