The Match transformation processing in the Hadoop environment depends on the engine that runs the transformation.

Match Transformation Support on the Blaze Engine

Mapping validation fails when the Match transformation is configured to write identity index data to database tables.
A Match transformation generates cluster ID values differently in native and Hadoop environments. In a Hadoop environment, the transformation appends a group ID value to the cluster ID.

Match Transformation Support on the Spark Engine

Mapping validation fails when the Match transformation is configured to write identity index data to database tables.
A Match transformation generates cluster ID values differently in native and Hadoop environments. In a Hadoop environment, the transformation appends a group ID value to the cluster ID.

Match Transformation Support on the Hive Engine

Mapping validation fails if a Match transformation specifies an identity match type.
A Match transformation generates cluster ID values differently in native and Hadoop environments. In a Hadoop environment, the transformation appends a group ID value to the cluster ID.
