cdh3 stopped working after linux kernel upgrade to 3.13. Have to figure out why. Temporarily make nopass until then. Maybe should port test to use CDH5 cluster. kernel upgrade part of making all systems same linux kernel rev. The new systems 181-190 were at 3.13. Kernel was at 3.2, which on 163 caused a hard hang yesterday with docker, which is only supported on 3.8+. So I wanted to move all systems to consistent 3.13 everywhere, to keep things simpler.
