There is a way only Spark use Java 8, Hadoop still use Java 7: spark-conf.jpg (58K) <https://mail.google.com/mail/u/0/?ui=2&ik=a9af0e7eb1&view=att&th=15a3f68a367de778&attid=0.1&disp=safe&realattid=f_iz6aduk80&zw>
By the way, I have a way to install any spark version on CM5.4 - CM5.7 by custom CSD <https://github.com/wangyum/cm_csds/tree/master/SPARK> and custom Spark parcel <https://github.com/wangyum/spark-parcel>.
