[PR] Using Flink 1.20.3, starting sql-client.sh throws 'Failed to start th… [doris]
Cocoyamsweetsnow opened a new pull request, #61070:
URL: https://github.com/apache/doris/pull/61070
…e embedded sql-gateway' error
### What problem does this PR solve?
Issue Number: close #60983
Related PR: None
Problem Summary:
在 Flink 1.20+ 中，`sql-client.sh` 的行为发生了重大变更：不再直接连接 JobManager
的 REST 端点，而是在本地启动一个嵌入式 SQL Gateway。该嵌入式网关在未显式配置
`sql-gateway.endpoint.rest.port` 时，会继承全局的 `rest.bind-port`（默认 8081）
作为自己的 REST 端口。
由于 JobManager 的 REST 端点已经占用了 8081，嵌入式 SQL Gateway 尝试绑定同一端口时
就会抛出以下异常：
java.net.BindException: Could not start rest endpoint on any port in port range 8081 at org.apache.flink.runtime.rest.RestServerEndpoint.start at org.apache.flink.table.gateway.SqlGateway.start
**修复方案：**
在 `samples/datalake/iceberg_and_paimon/data/flink-conf/flink-conf.yaml` 中新增
`sql-gateway.endpoint.rest.port: 9091`，为嵌入式 SQL Gateway 指定一个独立端口，
使其与 JobManager REST 端口（8081）隔离，避免端口冲突。
### Release note
When using Flink 1.20+ with `sql-client.sh`, add `sql-gateway.endpoint.rest.port`
configuration to avoid port conflict with JobManager's REST endpoint.
