> hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/src/main/native/src/util/Checksum.cc contains x86-only code and assumes it's going to work by default. The logic should be inverted so that it only uses the x86 code when built on x86 and otherwise defaults to the architecture-independent code. That will prevent changes having to be made for each new architecture.
