fluo-cluster
This module contains all code necessary to run Fluo on a YARN cluster using Apache Twill.
It was separated from fluo-core to keep dependencies (like Twill) out of Fluo clients which
depend on the fluo-core jar. It was also done to limit conflicts. For example, Twill
requires logback to be used but fluo-core requires log4j (due to zookeeper requiring it in
accumulo-minicluster).
