For now you can edit the nodetool script itself by adding
-Duser.home=/tmp as in "$JAVA" $JAVA_AGENT -cp "$CLASSPATH" -Xmx32m -Duser.home=/tmp -Dlogback.configurationFile=logback-tools.xml -Dstorage-config="$CASSANDRA_CONF" org.apache.cassandra.tools.NodeTool -p $JMX_PORT $ARGS if you like you can add an issue to jira.
