Hive Function Exceptions

Hive Function Exceptions

The Data Integration Service cannot push supported functions to Hive sources under certain conditions.
The Data Integration Service processes transformation logic for Hive sources when expressions contain supported functions with the following logic:
  • LTRIM includes space as the second argument.
  • RTRIM includes space as the second argument.
The Data Integration service cannot process the transformation logic for Hive sources when you use the following functions with the date datatype:
  • CONCAT
  • MAX
  • MIN
  • ROUND
  • TO_BIGINIT
  • TO_INTEGER
