Title:
  slaves file not present on yarn-master

Status in Juju Charms:
  Fix Committed

Bug description:
  Attempting to use /usr/lib/hadoop/sbin/[stop|start]-yarn.sh doesn't
  restart the nodemanagers.  This is because we do not have the
  /etc/hadoop/conf/slaves file on a standalone yarn master.  We need to
  sync this file from hdfs-master to yarn-master on every update.

  Alternatively, we can construct the slaves file on the yarn master
  just like we do for the hdfs master.  This is probably a better route
  since it's possible someone would have a datanode without a
  nodemanager (which would be an hdfs slave; not a yarn slave), and
  conversely, a nodemanager without a datanode (which would be a yarn
  slave; not an hdfs slave).
