Hi, over on the (not yet Apache-fied) REEF mailing list, we have people ask about running REEF examples on the Hortonworks sandbox. Surprisingly, that doesn't work.
I tracked down the issue to a rather fundamental one: REEF assumes that the usual Hadoop environment variables are set (HADOOP_HOME, HADOOP_CONF_DIR, ...) both at the client machine and for the AM and all containers launched. However, those aren't set in the sandbox install. Does this mean that the sandbox setup is broken or that we were doing it wrong when assuming that those environment variables are always set? Thanks, Markus
