[jira] [Created] (MAPREDUCE-6435) MapReduce client assumes the workd is x86

Alan Burlison created MAPREDUCE-6435:
----------------------------------------

             Summary: MapReduce client assumes the workd is x86
                 Key: MAPREDUCE-6435
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6435
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: client
    Affects Versions: 2.7.1
            Reporter: Alan Burlison


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.
