java.util.concurrent.CompletionException: org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: Slot request bulk is not fulfillable! Could not allocate the required slot within slot request timeout

1.无法分配所需的资源槽,资源槽请求超时!

导致flink-web上观察flink任务状态一直是created状态

解决:

yarn slot 满了，减少并发度
或者单个cpu使用率高，增加并发度， 减少单个并发内存

2. rest.port 端口被占用

Caused by: java.net.BindException: Could not start rest endpoint on any port in port range 39144    # 没有指定端口范围

解决: vim flink-conf.yaml 修改端口范围即可

The port to which the REST client connects to. If rest.bind-port has not been specified, then the server will bind to this port as well.

译: REST客户端连接到的端口。如果未指定REST.bind-port，则服务器也将绑定到此端口。
rest.port: 8087

Port range for the REST and web server to bind to

译: REST和web服务器要绑定到的端口范围

3. java.lang.VerifyError: Cannot inherit from final class

观察log日志信息发现是因为,flink中的cdc依赖问题

如果flink的lib目录下存在 ...cdc.jar 就是版本问题,需要和代码中使用的一致

如果不存在 ....cdc.jar 需要下载即可
