Allen Wittenauer commented on HADOOP-8737:
------------------------------------------

To be more concrete, those paths don't exist because that isn't where the Java 
lib directory lives.  For systems that support multi-arch/bitness (OS X, 
Solaris, etc), it will definitely pick the wrong library.
                
> cmake: always use JAVA_HOME to find libjvm.so, jni.h, jni_md.h

> We should always use the {{libjvm.so}}, {{jni.h}}, and {{jni_md.h}} under 
> {{JAVA_HOME}}, rather than trying to look for them in system paths.  Since we 
> compile with Maven, we know that we'll have a valid {{JAVA_HOME}} at all 
> times.  There is no point digging in system paths, and it can lead to host 
> contamination if the user has multiple JVMs installed.
