Hoya is a YARN an application that can deploy HBase cluster on YARN, monitor them and make them larger or smaller as desired -even while the cluster is running. Clusters can be stopped, "frozen" and restarted, "thawed" later.
It works on an Apache Hadoop 2.2 YARN cluster with Hbase 0.96.0 or later.
It also has some initial support for Apache Accumulo, though that code has not been tested at any scale.
