Github user paul-rogers commented on the issue: https://github.com/apache/drill/pull/558 Turns out the question was about: what does $DRILL_SITE mean. This is the name I use in documentation to refer to the new "site directory." For purposes of this fix, just replace "$DRILL_SITE" with "site directory" as a description of the place, outside of $DRILL_HOME, where config & jars can be put.
