我的问题能够解决来源于这两篇帖子 storm ui显示supervisor个数与实际不符的解决 storm ui显示supervisor个数与实际不符的解决
按理说我的集群UI界面应该显示10个slot两个Supervisor的,但是现在的数量只有实际开启数量的一半儿,明显是有问题的,查询了相关的资料后,发现自己的问题确实如上所说:
Try clearing the contents of storm.local.dir on both supervisors and restarting. This happens often for me when I clone a supervisor to a new instance and forget to reset the state.

I use 1 node for Zookeeper, 1 node for Nimbus and 2 nodes for Supervisors. After I started all of them, I can only see 1 supervisor up at the same time from the storm UI. If I fresh the UI again and again, the 1 supervisor which is displayed changes from 1 of the 2 to another. I tried read different manuals, blogs and guides, but failed to figure out why. Any idea? This is my config for storm: ########### These MUST be filled in for a storm configuration storm.zookeeper.servers: - "compute-0-7" #compute-0-7 is my zookeeper nimbus.host: 10.1.1.1 nimbus.childopts: "-Xmx1024m -Djava.net.preferIPv4Stack=true" ui.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true" supervisor.childopts: "-Djava.net.preferIPv4Stack=true" worker.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true" storm.zookeeper.port: 2181 storm.local.dir: "/users/staff/xuntao/storm/tmp/storm" storm.cluster.mode: "distributed" java.library.path: "/users/staff/xuntao/storm/zeromq/lib:/users/staff/xuntao/storm/jzmq/lib" supervisor.slots.ports: - 6700 - 6701 supervisor.enable: true按照博主的操作,清除storm.local.dir下的文件,再重启集群
删除文件后,重启集群,问题得到解决,节点信息恢复正常.
