why my storm UI can not display the supervisor's information while I can run my project successfully?

[Waldstein Wang]

Hi all,
my intention is setting up a cluster with 2 hosts. One is master running Zookeeper, nimbus and UI and the other one is slave running only supervisor.

The storm.yaml at master is :
########### These MUST be filled in for a storm configuration
# storm.zookeeper.servers:
#     - "localhost"
#
# nimbus.host: "localhost"
#
# storm.local.dir: "/wbh/Storm/workdir"
#
# supervisor.slots.ports: 
#        - 6700 
#        - 6701 
#        - 6702 
#        - 6703

The storm.yaml at slave is:
########### These MUST be filled in for a storm configuration
# storm.zookeeper.servers:
#     - "master's ip"
#
# nimbus.host: "master's ip"
#
# storm.local.dir: "/wbh/Storm/workdir"
#
# supervisor.slots.ports: 
#        - 6700 
#        - 6701 
#        - 6702 
#        - 6703

When I open http://localhost:8080 at master, the page shows:

It seems that UI did not know there is a supervisor on the slave host.

But when I test the WordCounter at both master and slave, it can run successfully. Why?!

Besides, when running at master, the log has following descriptions:
.......
1121 [main] INFO  backtype.storm.daemon.supervisor  - Starting supervisor with id ee32a3e5-0525-4314-8861-52a98836c988 at host "master's name"
.......

why storm start a supervisor at the master? I thought storm can use the supervisor at slave.

Thank you in advance

Hi,

I would like to ask whether the comment symbols were removed from the storm.yaml file. The '#' symbol indicates a commented line in this case.

If the contents in storm.yaml file are same as per your mail, please uncomment the required lines and save it. Please kill your topology, restart storm daemons and start your topology. I think this should solve your problem.

Richards is right, your config is not correct. You need to remove the # as step 1.

Also when you run the WordCounter, are you sure you are not running it in LocalCluster mode ? It seems you are doing that.

well, that seems to be a silly mistake.

Thank you!

I think I need to know more about LocalCluster mode.

Thank you!
