问题
I installed zookeeper on Ubuntu 14 but when run the command it fails. the command is: cat /var/log/kaa/* | grep ERROR
it shows: 2017-04-19 00:20:04,197 [main] ERROR o.k.k.s.n.s.i.KaNodeInitializationService - Failed to connect to Zookeeper within 5 minutes. Kaa Node Server will be stopped. 2017-04-19 00:45:39,668 [Kaa Node Server Shutdown Thread] ERROR o.k.k.s.c.s.a.AdminInitializationService - Error stopping Kaa Admin web server! 2017-04-19 00:45:39,668 [Kaa Node Server Shutdown Thread] ERROR o.k.k.s.c.u.KaaUncaughtExceptionHandler - Thread [Name: Kaa Node Server Shutdown Thread, id:67] uncaught exception: 2017-04-19 17:48:15,442 [main] ERROR o.k.k.s.n.s.i.KaaNodeInitializationService - Failed to connect to Zookeeper within 5 minutes. Kaa Node Server will be stopped.
But when i run this command it is ok: sudo /usr/share/zookeeper/bin/zkServer.sh start
What should i do? This is the project to deploy Kaa cluster
回答1:
check the zookeeper is running or not if not run it as a service and port should open to connect zk.
