Truncate Partitioned Hive Target Tables
Effective in version 10.2.1, you can truncate an external or managed Hive table with or without partitions.
Previously, you could design a mapping to truncate a Hive target table, but not an external, partitioned Hive target table.
For more information on truncating Hive targets, see the "Mapping Targets in the Hadoop Environment" chapter in the
Informatica Big Data Management 10.2.1 User Guide.
