Applies to:

Oracle Financial Services Analytical Applications Infrastructure - Version 7.3.3.3.0 and later
Information in this document applies to any platform.

Goal

We want to use the hive parameters in OFSAA mappings (UMM>DataMapping). For example,
1. set hive.exec.mode.local.auto=true; helps to bypass map reduce in case of small data sets.
2. set hive.exec.parallel=true; enables parallel execution of the various stages of a hive query.
3. set hive.autoconvert.join=true; tries to convert a join to map join wherever possible.
4. set hive.map.aggr=true; is used to improve performance of aggregation.

How to use these hive parameters in OFSAA ?
