You can read and write fixed-width and delimited file formats. You can read or write compressed files. You can read text files and binary file formats such as sequence file from HDFS. You can specify the compression format of the files. You can use the binary stream output of the complex file data object as input to a Data Processor transformation to parse the file.
You can define the following objects in an HDFS mapping:
Flat file data object or complex file data object operation as the source to read data from HDFS.
Flat file data object as the target to write data to HDFS or any target.
Validate and run the mapping. You can deploy the mapping and run it or add the mapping to a Mapping task in a workflow.
