> Since HIVE-14887,
> [Hadoop23Shims|https://github.com/apache/hive/blob/master/shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java]
> silently overrides e.g. hive.tez.container.size which is defined in
> data/conf/hive/llap/hive-site.xml. This way, the developer will have no idea
> about what happened after setting those values in the xml.
> My proposal:
> 1. don't set those values, unless they contain the default value (e.g.: -1
> for hive.tez.container.size)
> 2. put an INFO level log message about the override
> OR:
> put a comment in hive-site.xml and tez-site.xml files that shims override it
> while creating a tez mini cluster
