Complex File Targets on HDFS

Complex File Targets on HDFS

Use a PowerExchange for HDFS connection to write data to HDFS data objects.
The following table shows the complex files that a mapping can process within HDFS storage in the Hadoop environment:
File Type
Supported Formats
Supported Engines
Avro
  • Flat
  • Hierarchical
    1 2
  • Blaze
  • Spark
JSON
  • Flat
    1

1
To run on the Blaze engine, the complex file data object must be connected to a Data Processor transformation.
2
To run on the Spark engine, the complex file write operation must be enabled to project columns as complex data type.
