Subject Re: Is it possible to 'force' a topology ID to a specific value?
Date Sun, 14 Dec 2014 20:50:42 GMT
Why dont you use the storm list command and use the output to make up the
url.
That will give the topology name,

Else you can do a ls on storm local directory to get exact id of toplogy.

ls /home/storm/storm-local/nimbus/stormdist

Additionally you can query zookeeper for storm node directory and you will
get topology id from there.


Hope this helps.
