Subject [jira] Commented: (HIVE-1530) Include hive-default.xml and hive-log4j.properties in hive-common JAR
Date Fri, 13 Aug 2010 05:01:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12898080#action_12898080

Joydeep Sen Sarma commented on HIVE-1530:

ok - that makes sense. leave a hive-site.xml.sample and hive-log4j.properties.example in the
conf/. i agree with Ed's point about how difficult it is to figure out hadoop config variables
now and hadoop is worse off for it. commands are nice - but having a template is better. it's
easy to clone an example file and append/modify the default description to add site specific
notes. and one can grep.

we could autogenerate the hive-site.xml.sample from config variable metadata in the source
code. that would keep us in sync with code.

>             Project: Hadoop Hive
>          Issue Type: Improvement

> hive-common-*.jar should include hive-default.xml and hive-log4j.properties,
> and similarly hive-exec-*.jar should include hive-exec-log4j.properties. The
> hive-default.xml file that currently sits in the conf/ directory should be removed.
> Motivations for this change:
> * We explicitly tell users that they should never modify hive-default.xml yet give them
the opportunity to do so by placing the file in the conf dir.
> * Many users are familiar with the Hadoop configuration mechanism that does not require
*-default.xml files to be present in the HADOOP_CONF_DIR, and assume that the same is true
