Carl Steinbach commented on HIVE-1530:
--------------------------------------
bq. but users may want to modify the log4.properties files. how would do they
do that in the new arrangement?
Hive uses a classloader to get the hive-log4j and hive-exec-log4j property
resources. If a user wants to override the log4j properties that are bundled
with the JAR they only need to make sure that their copy appears first on the
CLASSPATH.
> Include hive-default.xml and hive-log4j.properties in hive-common JAR

> Key: HIVE-1530
> URL: https://issues.apache.org/jira/browse/HIVE-1530
> Project: Hadoop Hive
> Issue Type: Improvement
> Components: Configuration
> Reporter: Carl Steinbach
>
> 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 for HIVE_CONF_DIR.
