This isn't confirmed, but it looked like "externalEmit" failed on a DB node and worked on all other nodes
For DB nodes (unless they have the aleph2 service running), they use environment variables to get their FileContext reference, so it seems likely that this no longer works since HDP2.3.
Workaround is either to install /opt/aleph2-home/yarn-config/* or to turn off NodeManagers on the DB nodes
Need to turn off the API NodeManagers on a dev cluster, confirm, and then fix.
