----------------------------------------------------------------------
Just so it's on record so when someone hits this problem: this is fragile and
subject to breakage, regardless of the version of hadoop in play. It all
depends upon how users have HADOOP_CLASSPATH configured in hadoop-env.sh and
yarn-env.sh.

> MapReduce doesn't set the HADOOP_CLASSPATH for jar lib in distributed cache.

> We already set lib jars on distributed-cache to CLASSPATH. However, in some
> corner cases (like: MR local mode, Hive Map side local join, etc.), we need
> these jars on HADOOP_CLASSPATH so hadoop scripts can take it in launching
> runjar process.
