you can follow following page : http://bigdatafan.blogspot.in/2016/05/upgrade-java-to-jdk-8-on-cloudera-cdh.html additionally, update the symbolic link that from which java runs. For my cluster it was /usr/bin/java which I got from which java. You can remove the same and create a new link from the location where you will place new java version
