I create a redis cluster with docker-compose and when I try to connect the cluster from my local machine with a java app, which also docker is located in, but lettuce gets timeout while jedis connects to cluster. Lettuce connects to main servers which are 7001 7002 7003 and after that it discover other nodes and again try to connect them and gets time out. Here is my code.
Docker-compose.yml

QUESTION
Previously, we were using Redis with cluster mode disabled via AWS ElastiCache.
Our Java code using Jedis was pointing to the primary single node endpoint, which was used for reads and writes.
We've now enabled cluster mode.
We have now changed the code to point to the configuration endpoint of the new Redis cluster however it is now throwing errors whenever receiving requests, see below:
Redis Unavailable. Continue using the Queue requestMessage instead. org.springframework.data.redis.ClusterRedirectException: Redirect: slot 2356 to [ipaddress]:6379.; nested exception is redis.clients.jedis.exceptions.JedisMovedDataException: MOVED 2356 [ipaddress]:6379
Our configuration code is as below:
...ANSWER
Answered 2022-Feb-13 at 14:35Shouldn't just changing Jedis to point to the configuration endpoint be enough?
No, as the Redis client - Jedis in this instance - needs to be aware that it is connecting to a cluster and it currently isn't.
You are getting MOVED
as the Redis cluster is telling the client that the data being requested has now been 'resharded' to another node. Jedis, however, is not aware that a cluster is being used, and thus that there are any other nodes and therefore, can't even connect to them to retrieve data.
Do I need to change anything in my code?
You need to use JedisCluster
instead of JedisPool
for the discovery of the Redis nodes to happen & make the other relative changes within the codebase.
Note that you only need to reference the configuration endpoint:

QUESTION
I have a multimodule Maven project where parent pom is as follows
...ANSWER
Answered 2022-Jan-12 at 10:04You have declared 'org.springframework.boot' as the parent module of both modules. So if some jars and artifacts like 'com.amazonaws' do not exist in 'org.springframework.boot', they won't be resolved in your project. These dependencies are not announced in 'Spring' module in your project and whatever you have declared in it, can be found in 'org.springframework.boot', then resolved. If you do not declare a 'version' tag in your pom, I guess the version of the parent (here 2.6.1) will be considered for your module version.

As you can see, I have a simple default test. For some unknown reason for me, it does not load the application context, if I remove @SpringBootTest annotation everything works, but without it I cannot do bean injection, so I need this annotation.

...ANSWER
Answered 2022-Jan-07 at 10:36It seems that you have flyway dependency in your pom. When using @SpringbootTest, It will initialize the whole application context. According to the Springboot Autoconfigure mechanism, the application detects the Flyway module and tries to create a bean named flyway:
Error creating bean with name 'flyway'
And then when constructing the flyway bean, the flyway Factory needs a datasource bean.
QUESTION
Recently i work with redis and using jedis. In redis version 6, we can set required password mode for sentinels. I have 3 working sentinels, can connect and authen throught redis-cli. But using jedis, i can't connect to the sentinel with this warning:
Cannot get master address from sentinel running @ 127.0.0.1:26379. Reason: redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.. Trying next one.
Cannot get master address from sentinel running @ 127.0.0.1:36379. Reason: redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.. Trying next one.

And this error:
All sentinels down, cannot determine where is mymaster master is running...
Here is my code:
...ANSWER
Answered 2021-Dec-23 at 12:32Your sentinel nodes are password protected. You would have to provide AUTH parameters to connect to sentinel nodes.
Update:
Password you're providing acts as the password for master node. To avoid NOAUTH error from sentinel nodes, you have to provide the password for sentinel nodes. Look for any constructor that takes the password for sentinel nodes. That parameter is generally named sentinelPassword
. There are several such constructors, simplest of those is
