Colin Patrick McCabe commented on HADOOP-8737:
----------------------------------------------
I am going to post a new version of the patch that surrounds this code in
{code}
IF("${CMAKE_SYSTEM}" MATCHES "Linux")
{code}
On non-Linux platforms, we can fall back on the old method of detecting JNI
installations.
Allen, I believe this will address your concerns.
> 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.
