   YCSB results show mostly within variance I think, but possibly some improvement for read heavy workloads (Workload C) and degradation for the scan heavy one (Workload E). This was a cluster with one master, five regionservers, on AWS M5 class instances, Hadoop 2.10.0, HBase 1.7.0-SNAPSHOT, YCSB 0.18 on a separate client box.
