Subject [jira] Commented: (HIVE-1339) Allow setting of per-job configuration properties for JDBC driver
Date Thu, 06 May 2010 20:12:53 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864903#action_12864903
] 

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.

> 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.
