Sources in a Hadoop Environment

Sources in a Hadoop Environment

Due to the differences between the native environment and a Hadoop environment, you can only push mappings with certain sources to a Hadoop environment. Some of the sources that are valid in mappings in a Hadoop environment have restrictions.
You can run mappings with the following sources in a Hadoop environment:
  • IBM DB2
  • Flat file
  • HBase
  • HDFS complex file
  • HDFS flat file
  • Hive
  • ODBC
  • Oracle
  • Teradata
  • Netezza
The Blaze engine might not support all sources in a Hadoop environment. When the Data Integration Service finds a source that is not supported by the Blaze engine, it defaults to the Hive engine and runs the mapping on the Hadoop cluster.
