ERR SELECT is not allowed in cluster mode

redis version 4.0.9
Redis cluster can not use this tool to get data ？

When using Redis Cluster, the SELECT command cannot be used, since Redis Cluster only supports database zero. In the case of Redis Cluster, having multiple databases would be useless, and a worthless source of complexity, because anyway commands operating atomically on a single database would not be possible with the Redis Cluster design and goals.
