add new data node failed: incompatible build version (CDH3)
The version for the current cluster is Cloudera 0.20.2+228
A newer version of CDH 0.20.2+320 is installed on a new machine to be used as a new datanode. But it failed to join the cluster and the log is shown below. So, the build version of a data node has to be exactly the same as the namenode or older?

Thanks Ted. I guess the simplest way to avoid breaking anything for now I can try yum downgrade the new version to the older one on the new data node machine. Hope that works.
Thanks,
Michael

CDH 0.20.2+320 isn't compatible with 0.20.2+228
You need to upgrade whole cluster.
