Hi, could you please refer to release notes again, there's said these two versions are not compatible so far
*http://kylin.apache.org/blog/2016/03/17/release-v1.5.0/ <http://kylin.apache.org/blog/2016/03/17/release-v1.5.0/>* *Upgrade* *This version is not backward compatible*. The format of cube and metadata has been refactored in order to get times of performance improvement. We recommend this version, but does not suggest upgrade from previous deployment directly. A clean and new deployment of this version is strongly recommended. If you have to upgrade from previous deployment, an upgrade guide will be provided by community later. Thanks.
