      Description

      As described here: https://hadoop.apache.org/docs/current/api/org/apache/hadoop/conf/Configuration.html, hadoop -site.xml files support variable substitution from environment variables.

      It appears that bash variables defined in hadoop-env.sh are available in the actual hadoop processes, but for some reason that is not the case with cdap. Possibly due to the su, but needs some research.

      Note that https://issues.cask.co/browse/CDAP-12181 prevents any variable expansion from working
