Thanks.

I downloaded verion 0.20.0 and checked it: JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} -Xmx32m org.apache.hadoop.util.PlatformName | sed -e "s/ /_/g"` Here they are just hard coding it to -Xmx32m, which is better. If I have my HADOOP_HEAPSIZE cranked way up on a big server, I don't want to use this value for getting the JAVA_PLATFORM! The developers already know. I downloaded verion 0.20.0 and checked it:
