Expression Transformation Support on the Hive Engine

Expression Transformation Support on the Hive Engine

  • The transformation contains stateful variable ports.
  • The transformation contains unsupported functions in an expression.
An Expression transformation with a user-defined function returns a null value for rows that have an exception error in the function.
