Alan Burlison commented on HADOOP-11505:
----------------------------------------
It's looking in /usr/include for one of endian.h, sys/endian.h or
sys/byteorder.h, and then for either be16toh or BSWAP_64. If the include file
is in a different place on OSX or the macros are called something different
then no, it won't work. I don't have access to OSX to check, but as long as
there's a way to define the HADOOP_XXX macros in
hadoop-common-project/hadoop-common/src/CMakeLists.txt then the rest should
just work - everything else in the patch uses the macros that are
probed/configured by CMake.
> hadoop-mapreduce-client-nativetask uses bswap where be32toh is needed,
> doesn't work on non-x86

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some
> cases. Also, on some alternate, non-x86, non-ARM architectures the generated
> code is incorrect. Thanks to Steve Loughran and Edward Nevill for finding
> this.
