That is possible, as long as the default scheduler is allowed to deploy topologies to **all** servers (ie, your special servers are available to default scheduler, too).
(At least I think no, maybe it is even possible to exclude your special servers -- see comment below.) For this, you can instantiate the default scheduler within your custom one (or let you custom inherit from default). Each time, you get a scheduling request, you just decide if you want to forward the request to the default scheduler, or take care of it in you custom implementation. (If you are able to modify the cluster meta data about about available supervisors before you do the forward call to default scheduler, you might be able to hide your special servers from the default scheduler, too.) -Matthias On 04/21/2016 12:08 PM, Susana González wrote: > Hi, > > As Matthias says, you need to implement your own scheduler and use some > metadata in the storm.yaml file.
