Alan Burlison commented on HADOOP-11665:
----------------------------------------

Rather than depending on compiler-specific macros a better approach might be to 
use CMake's endian checks and pass in the appropriate -D flag as part of the 
compiler invocation. See 
http://www.cmake.org/cmake/help/v3.0/module/TestBigEndian.html

> Provide and unify cross platform byteorder support in native code
