[~agoncharuk][~akalashnikov]

Folks, any updates here? Should we include this issue to the 2.8 release or can move it to
the next?

> In our project we need to deploy custom compute tasks into cluster without cluster restart
and p2p class loading.  
> I try to use org.apache.ignite.spi.deployment.uri.UriDeploumentSpi for that purpose,
but I have a problem.
> I have simple Ignite Service and Ignite Compute Task which use it throught @ServiceResource.
> This ComputeTask located into .gar file which was deployed via UriDeploumentSpi.
> If I have service implementation on each node(node singleton service) then it works great.

> But if I deploy service as a cluster singleton then task executes correctly only on node
with this service. 
> On other nodes @ServiceResource returns ServiceProxy that throws exception on service
remote method invokation (lambda with service call cannot be deployed):
> {code}

> class org.apache.ignite.IgniteDeploymentException: Failed to auto-deploy task (was task
(re|un)deployed?): class org.apache.ignite.internal.processors.service.GridServiceProcessor$ServiceTopologyCallable
> {code}
> Problem works as follows:
> - Ignite has to determine which node has deployed service, by name.
> - Ignite has to send ServiceTopologyCallable task.
> - Ignite tries to deploy ServiceTopologyCallable task using UriDeploymentSpi.
> - UriDeploymentSpi doesn't have it obviously, but it also tries to fallback towards "CLASS"
loading from local ClassLoader
> - Which fails because it is told that ServiceTopologyCallable comes from its classloader
and not from the local one!
> So I'm at loss where it should be fixed properly. It is also sad that we are using all
that deploy pipeline to handle IgniteInternal tasks, but there obviously are non-internal
local tasks which might be affected by same problem.
