      Description

      Sometime during the last week, someone committed a change to:

      hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/pom.xml

      that inserted a -m32 in:

      <configureEnvironment>
      <property>
      <name>CFLAGS</name>
      <value>-DHADOOP_CONF_DIR=${container-executor.conf.dir} -m32</value>

      This breaks the build on 64-bit systems that do not have 32-bit libraries installed. The change was actually not required as 64-bit support for JNI and JVMs is readily available and installed by default on many 64-bit systems. Removing the flag results in a completed and functional build.

      If mandating 32-bit builds is desired, then a better solution would be to provide a configure flag such as -DHADOOP_32bit_MODE, perhaps with a corresponding flag for 64-bit. Regardless, locking the system to 32-bit builds seems a tad extreme.
