cachesync.Broadcaster:172 : error running wiping java.lang.IllegalArgumentException

>From the Downloads page I can only see apache-kylin-2.1.0-bin-cdh*57* .tar.gz Are there more current builds .. like for CDH 5.*12*? If not, does it make sense to build Kylin myself? (not sure what could be an advantage to have a build specific to latest CDH build?) Thank you, Ruslan
