Alan Burlison commented on HADOOP-11505:
----------------------------------------
Yes, I can do that. We already have HadoopCommon.cmake and HadoopJNI.cmake in
hadoop-common-project/hadoop-common, I suggest putting the new CMake module in
there (HadoopEndian.cmake?) and parameterising it with an output directory in
which to place the generated hadoop_endian.h file. It should be fairly
straightforward to do as it's basically just a case of factoring out the code
I've already written to generate the endinanness header and adding in calls to
it from existing CMake files.

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some
