Subject [jira] [Commented] (HIVE-4648) Add ability to set hadoop conf overrides in JDBC for HiveServer2
Date Mon, 03 Jun 2013 17:59:21 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13673367#comment-13673367
] 

Shreepadma Venugopalan commented on HIVE-4648:
----------------------------------------------

[~harisekhon]: It is possible to set and unset config variables through JDBC that can be set/unset
through the command line. To do so, you'd need to do an execute statement with "set config.var
= value". To set the scratch dir, you can do the following in JDBC,

{noformat}
statement.execute("set hive.exec.scratchdir = /tmp/mydir");
{noformat}

Note that this property is set for the particular JDBC connection.

> It's possible in BeeLine to specify set command overides of hadoop config variables,
but I haven't seen any example code of how to do this in JDBC with HiveServer2.
> We need an ability to specify hadoop conf overrides on a per session basis or even half
way through the session. See this Hive ticket for some background:
