[jira] [Commented] (IGNITE-8134) Services can't be deployed on servers outside of baseline topology

["Dmitriy Setrakyan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-8134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16425651#comment-16425651 ] 

Dmitriy Setrakyan commented on IGNITE-8134:
-------------------------------------------

Service deployment should not depend on baseline at all and services should be deployed once the cluster is activated.

> 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:
> =====================
> 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) { }
