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/

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.

Best Regards!

Hi all, 

kylin 1.5.0 has been released. I try to update kylin 1.2. to 1.5.0 following http://kylin.apache.org/docs15/howto/howto_upgrade.html. 

After back 1.2 meta, I run 

$KYLIN_HOME/bin/kylin.sh  org.apache.kylin.cube.upgrade.entry.CubeMetadataUpgradeEntry_v_1_5_1 <path_of_BACKUP_FOLDER>

Error Msg return: 

Could not find or load main class org.apache.kylin.cube.upgrade.entry.CubeMetadataUpgradeEntry_v_1_5_1

why ?
