描述
启动Flink任务的时候, 报错Could not deploy Yarn job cluster, 查看yarn logs -applicationId xxx发现BindException, 查看jobmanager所在机器占用端口过多, 导致启动任务失败, kill掉异常进程后启动正常.

解决步骤
- 日志中Trying to start actor system后面会有异常的host, 去到这台机器查看端口情况,
cat /proc/sys/net/ipv4/ip_local_port_range查看可用访问, 默认是32768-60999, 可用端口约为28000,netstat -anp | wc -l查看目前连接数, 如果远远超过这个数可能某个进程占用了大量的端口, 导致无法分配, kill掉这个异常的进程 - 如果步骤1端口范围正常, 可尝试修改
flink-conf.yaml配置, 加上yarn.application-master.port : 32768-60999
