> MAPREDUCE-3880 specifies that {{-m32}} be passed to gcc to ensure that a 32-bit binary is built. On my Amazon Linux with a x86_64 architecture, I could not build the native container-executor because the configure script exited with an error when trying to use gcc (version 4.4.5) with this flag.
> Adds a comment to {{hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/pom.xml}} regarding package requirement for glibc-devel.i686 or glibc-devel.i386 package on yum-based (RHEL, Centos, Amazon) Linux distributions.
