Subject [jira] Created: (COMDEV-12) JAVA_PLATFORM in hadoop shell script lacks HADOOP_OPTS

JAVA_PLATFORM in hadoop shell script lacks HADOOP_OPTS

                 Key: COMDEV-12
             Project:  	 Community Development 
          Issue Type: Bug
            Reporter: Allen Wittenauer

It appears to be expected behavior to be able to set the bitness in HADOOP_OPTS as well as
other java executable options.  However these options are not passed onto the JAVA_PLATFORM
test used to configure the java.library.path at run time:

  JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} -Xmx32m org.apache.hadoop.util.PlatformName
| sed -e "s/ /_/g"`

If a user passes "-d64" to force 64-bit (at least on Solaris), this option is not sent to
this code.  Instead of returning "SunOS-amd64-64" as expected for 64-bit, it still returns
"SunOS-x86-32" for 32-bit.  Thus causing native compression to fail.
