-----------------------------------------
Hi [~xkrogen]. Thanks for your review and providing the information!
Actually, when using hadoop-dynamometer(latest trunk) with the patch, I have
confirmed that HDP-2.6(hadoop-2.7.3) cluster just runs successfully. Though I
haven't confirmed workload jobs yet.
