I’m trying to upgrade from the HDP 2.1 to HDP 2.2 stack. Somewhere, I must have made a mistake because some configurations seem to be wrong (for instance, the wrong class name for the timeline server, and when I try to start region servers they complain that JAVA_HOME is undefined and they cannot find the JDK).
I tried rerunning the upgradeHelper.py update-configs command a second time, but it fails with lots of verification errors. Can this script only be run once? How do I determine if my configurations are the correct ones? Thanks. Brian
