Subject [jira] [Commented] (HIVE-19767) HiveServer2 should take hiveconf for non Hive properties
Date Wed, 06 Jun 2018 13:50:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-19767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16503320#comment-16503320

Szehon Ho commented on HIVE-19767:
----------------------------------

[~thejas] Sorry to bother , but as you are the original author of adding hiveconf to hiveserver2,
do you think this change makes sense and if this is the way you would go about it?  Seems
there is a bit of legacy code of setting them via environment variables that I did not want
to touch.

> The -hiveconf command line option works in HiveServer2 with properties in HiveConf.java,
but not so well with other properties (like mapred properties or spark properties to control
underlying execution engine, or custom properties understood by custom listeners)
> It is inconsistent with HiveCLI.
> HiveCLI behavior:
> {noformat}
> ./bin/hive --hiveconf a=b
> hive> set a;
> a=b {noformat}
> HiveServer2 behavior:
> {noformat}
> ./bin/hiveserver2 --hiveconf a=b
> beeline> set a;
> +-----------------+
> |       set       |
> +-----------------+
> | a is undefined  |
> +-----------------+{noformat}
> Although it is possible to set up hive-site.xml or even mapred-site.xml to fill in the
relevant properties, it is more convenient when testing HS2 with different configuration to
be able to use --hiveconf to change on the fly.
