HDFS-1150 (https://issues.apache.org/jira/browse/Hdfs-1150), part of the
security initiative, is a rather big change to the way Datanodes are
started in a secure environment and the resources needed to start one.
I want to make sure the community gets a chance to review the approach
we're taking - and the rather innocuous title may not convey the change
we're looking at.
The jsvc approach we've taken appears to be working and we're going to
commit it to the Y20 branch, but more comments are certainly welcome.
