JeremyXin opened a new issue, #9865: URL: https://github.com/apache/seatunnel/issues/9865
### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened Writing the set data in use redis cluster pattern, perform error: JedisConnectionException: Failed to connect to any host resolved for DNS name. After analysis, it was found that there is a bug in the batchWriteSet method of the RedisClusterClient class. The jedis object originally passed in the method has not been initialized, resulting in the Connection of the Jedis object not being initialized, which leads to the bug ### SeaTunnel Version 2.3.11 ### SeaTunnel Config ```conf env { parallelism = 1 job.mode = "BATCH" } source{ Localfile { path = "xxx/seatunnel/config/st-redis-test.json" file_format_type = "json" schema { fields { id = int name = string } } } } sink { Redis { nodes = ["xxx:6371","xxx:6372","xxx:6371","xxx:6372","xxx:6371","xxx:6372"] mode = "cluster" auth = "xxx" key = "redis-custom-key-{name}" value_field = "id" support_custom_key = true data_type = set expire = 300 } } ``` ### Running Command ```shell sh bin/seatunnel.sh --config config/v2.batch.redis.template -m local ``` ### Error Exception ```log Caused by: org.apache.seatunnel.common.utils.SeaTunnelException: redis.clients.jedis.exceptions.JedisConnectionException: Failed to connect to any host resolved for DNS name. at redis.clients.jedis.DefaultJedisSocketFactory.connectToFirstSuccessfulHost(DefaultJedisSocketFactory.java:63) at redis.clients.jedis.DefaultJedisSocketFactory.createSocket(DefaultJedisSocketFactory.java:87) at redis.clients.jedis.Connection.connect(Connection.java:180) at redis.clients.jedis.Connection.sendCommand(Connection.java:152) at redis.clients.jedis.Connection.sendCommand(Connection.java:147) at redis.clients.jedis.Jedis.select(Jedis.java:800) at org.apache.seatunnel.connectors.seatunnel.redis.config.RedisParameters.buildJedis(RedisParameters.java:228) at org.apache.seatunnel.connectors.seatunnel.redis.config.RedisParameters.buildRedisClient(RedisParameters.java:149) at org.apache.seatunnel.connectors.seatunnel.redis.sink.RedisSinkWriter.<init>(RedisSinkWriter.java:69) at org.apache.seatunnel.connectors.seatunnel.redis.sink.RedisSink.createWriter(RedisSink.java:54) at org.apache.seatunnel.connectors.seatunnel.redis.sink.RedisSink.createWriter(RedisSink.java:33) at org.apache.seatunnel.api.sink.multitablesink.MultiTableSink.createWriter(MultiTableSink.java:82) at org.apache.seatunnel.engine.server.task.flow.SinkFlowLifeCycle.restoreState(SinkFlowLifeCycle.java:343) at org.apache.seatunnel.engine.server.task.SeaTunnelTask.lambda$restoreState$16(SeaTunnelTask.java:401) at java.util.stream.ForEachOps$ForEachOp$OfRef.accept(ForEachOps.java:184) at java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:193) at java.util.stream.ReferencePipeline$2$1.accept(ReferencePipeline.java:175) at java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1382) at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:481) at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:471) at java.util.stream.ForEachOps$ForEachOp.evaluateSequential(ForEachOps.java:151) at java.util.stream.ForEachOps$ForEachOp$OfRef.evaluateSequential(ForEachOps.java:174) at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.util.stream.ReferencePipeline.forEach(ReferencePipeline.java:418) at org.apache.seatunnel.engine.server.task.SeaTunnelTask.restoreState(SeaTunnelTask.java:398) at org.apache.seatunnel.engine.server.checkpoint.operation.NotifyTaskRestoreOperation.lambda$null$0(NotifyTaskRestoreOperation.java:107) at java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1626) at org.apache.seatunnel.api.tracing.MDCRunnable.run(MDCRunnable.java:43) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Suppressed: java.net.ConnectException: Connection refused (Connection refused) at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at redis.clients.jedis.DefaultJedisSocketFactory.connectToFirstSuccessfulHost(DefaultJedisSocketFactory.java:73) ... 30 more ... 12 more at org.apache.seatunnel.core.starter.seatunnel.command.ClientExecuteCommand.execute(ClientExecuteCommand.java:220) ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots  ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
