There is no java client in the same level with hector, hector is the best and there is work in progress in hector side to support cql. I saw cql commits for hector in github this month, but doesn't know it's final state. You can ask it to hector users group http://groups.google.com/group/hector-users
Also there is a very simple object mapper in hector
