[jira] Created: (HIVE-1339) Allow setting of per-job configuration
properties for JDBC driver
Allow setting of per-job configuration properties for JDBC driver
-----------------------------------------------------------------
Key: HIVE-1339
URL: https://issues.apache.org/jira/browse/HIVE-1339
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 ;
hive> SELECT a, b, c FROM t WHERE a < 10 ;
Currently, there is no way to set per-job configuration parameters (e.g., mapred.reduce.tasks) via the JDBC client.

[jira] Commented: (HIVE-1339) Allow setting of per-job

----------------------------------
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.

----------------------------------
Have you tried just executing the "set" command via JDBC's Statement.execute? It is actually processed by ql (not cli) so it should work; at least it did when I tested on trunk via sqlline.
It would still be nice to be able to specify these as JDBC connection properties though.

---------------------------------------
Did you mean the other way around?
CLI processes the 'set' commands, ql runs SQL statements...
