Per e-mail thread discussion 1.7 JDK was manually added before cluster upgrade, and was present within custom local yum repo at the site.
CM/CDH will pick the later JDK present to use. Per Phillp L:
Yes. We ask yum to install jdk and if yum decides that it's appropriate to install a newer version of jdk than is already installed, that is what it will do.
