------------------------------------------
The fix is ready. Please review: [https://github.com/apache/ignite/pull/3863]
> Services can't be deployed on servers outside of baseline topology
> ------------------------------------------------------------------
>
> Key: IGNITE-8134
> URL: https://issues.apache.org/jira/browse/IGNITE-8134
> Project: Ignite
> Issue Type: Bug
> Components: managed services, persistence
> Reporter: Stanislav Lukyanov
> Assignee: Denis Mekhanikov
> Priority: Major
> Fix For: 2.6
>
>
> If a node is not a part of the baseline topology, the services will never be
> deployed on it. In particular, if that node calls a synchronous deploy*
> method, the method will hang.
> After the node is added to the baseline, all previously initiated
> deployments succeed (and deploy* methods return).
> It seems that the issue is with the continuous query started by the
> GridServiceProcessor on the ignite-sys-cache.
> Example:
> =====================
> {code}
> public class BltServicesBug {
> public static void main(String[] args) {
> // start one node
> IgniteConfiguration cfg1 = new IgniteConfiguration()
> .setIgniteInstanceName("node1")
> .setDataStorageConfiguration(
> new DataStorageConfiguration()
> .setDefaultDataRegionConfiguration(
> new DataRegionConfiguration()
> .setPersistenceEnabled(true)
> )
> );
> try (Ignite ignite1 = Ignition.start(cfg1)) {
> // activate and set baseline topology
> ignite1.cluster().active(true);
> // start another node
> IgniteConfiguration cfg2 = new IgniteConfiguration(cfg1)
> .setIgniteInstanceName("node2");
> try (Ignite ignite2 = Ignition.start(cfg2)) {
> // try to deploy a service;
> // this call hangs until the second node is added to the BLT
> (e.g. externally via control.sh)
> ignite2.services().deployNodeSingleton("myService", new
> MyServiceImpl()); System.out.println(">>>>> Deployed"); }
> }
> }
> private static class MyServiceImpl implements Service {
> @Override public void cancel(ServiceContext ctx) { }
> @Override public void init(ServiceContext ctx) { }
> @Override public void execute(ServiceContext ctx) { }
> }
> }
> }
> {code}
> =====================
