Arpit Gupta commented on HADOOP-8132:
-------------------------------------
The platform information is determined using
{code}
JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} -Xmx32m
${HADOOP_JAVA_PLATFORM_OPTS} org.apache.hadoop.util.PlatformName | sed -e "s/
/_/g"`
{code}
So unless this class returns x86_64 we should not make this change.
