> 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.
