Subject [jira] [Commented] (HIVE-7497) Fix some default values in HiveConf
Date Tue, 29 Jul 2014 09:07:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14077536#comment-14077536
] 

Lefty Leverenz commented on HIVE-7497:
--------------------------------------

This renames configuration parameter *hive.global.init.file.location* (created in HIVE-5160)
to *hive.server2.global.init.file.location* and revises its description, as well as changing
its default from System.getenv("HIVE_CONF_DIR") to "$\{env:HIVE_CONF_DIR\}" and changing the
default of configuration parameter *hive.hwi.war.file* from "$\{system:HWI_WAR_FILE\}" to
"$\{env:HWI_WAR_FILE\}".  

*hive.server2.global.init.file.location* needs to be documented in two places, with version
information and a link to this JIRA ticket:

* [Hive Web Interface -- Configuration | https://cwiki.apache.org/confluence/display/Hive/HiveWebInterface#HiveWebInterface-Configuration]
* [Configuration Properties -- Hive Web Interface (HWI) | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-HiveWebInterface(HWI)]

But it's not clear to me whether the default value changes need any user doc updates -- do
they?

> HIVE-5160 resolves an env variable at runtime via calling System.getenv(). As long as
the variable is not defined when you run the build null is returned and the path is not placed
in the hive-default,template. However if it is defined it will populate hive-default.template
with a path which will be different based on the user running the build. We should use $\{system:HIVE_CONF_DIR\}
instead.
