Failed to establish connection to redis cluster mode deployment #3613
Description
Expected behavior
Jedis java client should connect with Redis cluster deployment.
Actual behavior
Jedis java client failed to connect with Redis cluster deployment.
Steps to reproduce:
- Install redis cluster deployment in kubernetes cluster (
helm install redis oci://registry-1.docker.io/bitnamicharts/redis-cluster -n redis) - Portforward 6379 to local (
kubectl port-forward svc/redis-redis-cluster 6379 -n redis) - Execute Jedis java client
