An alternative to this would be to take over creating the JVM ourselves using 
JNI_CreateJavaVM. Currently we rely on the HDFS C interface to do that for us. 
If we did it ourselves, we'd need to recreate some of the classpath logic and 
include LIBHDFS_OPTS.

However HDFS calls JNI_CreateJavaVM with vm_args.ignoreUnrecognized=1, and 
LIBHDFS_OPTS gets transformed into vm_args.options. Using LIBHDFS_OPTS rather 
than JAVA_TOOL_OPTIONS would allow us to supply unknown parameters, and skip 
checking the Java version.

Yeah, that would make sense.
