> When TLS is enabled in the Redis/Valkey service, impalad can't read/write HBO stats in the cache. However, the warning logs are misleading:
> {code:java}
> RedisCacheBackend.java:125] Failed to put HBO key 5a848e574b16a01e6fe5db09dceddc2f (stats type CARDINALITY) to Redis: java.net.SocketTimeoutException: Read timed out{code}
> We need to abort Impalad if HBO is configured to use Redis/Valkey but fail to read/write from them.
> Also need to add TLS support in RedisCacheBackend.
