    Description

      If you try running HBase built with Java 8 on a Java 7 JRE, then processes will fail early with:

      java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;

      I came across this incidentally. I suppose we should consider documenting this in the manual in the Troubleshooting section.
