Zhong Yanghong commented on KYLIN-3326:
---------------------------------------
Currently when call {{updateMeta}} in {{CubeMigrationCLI}}, it gets all the
target cluster's rest servers and then call rest to update the metadata for
each server. This may lead to an issue in case of that the target cluster
expose only a vip to others. We can not expect that all the nodes in the source
cluster can successfully connect to all the nodes in the target cluster.
Therefore, I think it's better to expose only a interface to others like
{{announceWipeCache}} in {{CacheController}}.
> Better way to update migration target cluster's metadata after cube migration
