> hadoop-0.20.0-dev-core.jar contains log4j.properties file, and I think that's the one
hadoop is picking up. I modified both conf/hive-log4j.properties and hadoopcore/conf/log4j.properties,
but hadoop still printed INFO messages to stderr.

still show up. How can I get rid of them?

> When we run the tests - we run in hadoop 'local' mode - and in this mode, we run map-reduce
jobs by invoking 'hadoop jar ... ExecDriver' cmd line. this was done because we had some issues
submitting map-reduce jobs directly (from same jvm) in local mode that we could not resolve.
> The issue is that when we invoke 'hadoop jar ... ExecDriver' - we don't control log4j
via hive-log4j. one thing u can try is changing the hadoop's log4j.properties that hive is
picking up (probably hadoopcore/conf/log4j.properties).
> Revisiting this after a long time - I think this can be fixed with some changes to MapRedTask.java
(need to add hive-log4j.properties to hadoop classpath here and then reset log4j using this
in execdriver). Feel free to file a jira if this is too irritating ..
