ErrorCode:[STARROCKS-04], ErrorDescription:[Create StarRocks BE reader failed]

使用ST docker 集群模式 从starrock1 存算一体 到另外一个starrocks2集群。这里配置了FE的http port 8080,但是转发请求不到BE,连接失败。容器都在一个网络。

Start with the StarRocks source configuration, especially nodeUrls and backend-urls, and then inspect StarRocksBeReadClient.java:82-85 where the BE socket failure is reported. Reproduce the Docker cluster setup and verify which BE address and port the job attempts to reach. Done means the SeaTunnel job can read the StarRocks table without the STARROCKS-04 connection-refused error.
