             Summary: JNI build should use default cmake FindJNI.cmake

    Affects Versions: 2.7.0

----------
Why does  hadoop-common-project/hadoop-common/src/CMakeLists.txt use JNIFlags.cmake in the same directory to set things up for JNI 
compilation rather than FindJNI.cmake, which comes as a standard cmake 
module? The checks in JNIFlags.cmake make several assumptions that I 
believe are only correct on Linux whereas I'd expect FindJNI.cmake to be 
more platform-independent.
----------
Just checked the repo of cmake and it turns out that FindJNI.cmake is
available even before cmake 2.4. I think it makes sense to file a bug
to replace it to the standard cmake module. Can you please file a jira
for this?

This also applies to hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/src/JNIFlags.cmake
