Complex File Sources on MapR-FS

Complex File Sources on MapR-FS

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

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 read operation must be enabled to project columns as complex data type.
