John Sichi commented on HIVE-1339:
----------------------------------
At least in trunk, the processing for the set command is in this class:
ql/src/java/org/apache/hadoop/hive/ql/processors/SetProcessor.java
CLI just wraps this.
> Allow setting of per-job configuration properties for JDBC driver

> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Clients
> Affects Versions: 0.4.0
> Reporter: Patrick Angeles

> From the CLI you can do:
> hive> set mapred.reduce.tasks = 5 ;

> Currently, there is no way to set per-job configuration parameters (e.g.,
> mapred.reduce.tasks) via the JDBC client.
