5.airflow问题

Traceback (most recent call last):

    return getattr(self._sock,name)(*args)
socket.error: [Errno 98] Address already in use

上面报了WORKER_LOG_SERVER_PORT这个，查下配置文件，是celeryexecutor像master合并日志的端口。
用root执行：

[root@bqdpsit1 ~]# netstat -apn | grep 8793
tcp        0      0 0.0.0.0:8793            0.0.0.0:*               LISTEN      85717/airflow serve 
[root@bqdpsit1 ~]# 
[root@bqdpsit1 ~]# ps -ef|grep 85717
root      85717      1  0 09:33 ?        00:00:01 /usr/bin/python /usr/bin/airflow serve_logs
root      90578  90367  0 09:58 pts/15   00:00:00 grep --color=auto 85717
[root@bqdpsit1 ~]# kill 85717

可以看到原因是：之前错误的用root执行了airflow worker命令，启动了一个服务，占了这个端口。kill掉后用bqadm启动airflow worker即可。
