Description

Was testing Phoenix support in one of my projects when I hit this issue with performance.py (cut & pasting for people web searching).

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/phoenix/util/PhoenixRuntime : Unsupported major.minor version 51.0

Could not find the main class: org.apache.phoenix.util.PhoenixRuntime.  Program will exit.

This is of course the common error indicating that you are using an older version of java to run something compiled with a newer version. But I was setting JAVA_HOME to an appropriate Java 1.7 path.

I eventually realized the issue was performance.py wasn't honoring the environment variable JAVA_HOME and picking up an older java version sitting in /usr/bin, where as queryserver.py does honor JAVA_HOME.

I can / will produce a patch, but can't right now. Thought I'd post this bug today for people web searching and in case someone else wants to beat me to it.
