Dmitriy Pavlov commented on IGNITE-8774:
----------------------------------------
Remaining test failures seems to come from reasons not related to the issue:
https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=8689176344607253190&branch=pull%2F4243%2Fhead&tab=testDetails&branch_IgniteTests24Java8=__all_branches__
Failed without changes
https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=9042263396020992120&branch=pull%2F4243%2Fhead&tab=testDetails
seems to be fixed recently and unmuted
https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=4219534437120988940&branch=pull%2F4243%2Fhead&tab=testDetails
came from obolete suite, which will be removed soon.
So I think TC status can be considered as OK.
> Daemon moves cluster to compatibility mode when joins

> Key: IGNITE-8774
> URL: https://issues.apache.org/jira/browse/IGNITE-8774
> Project: Ignite
> Issue Type: Bug
> Reporter: Stanislav Lukyanov
> Assignee: Aleksey Plekhanov
> Priority: Major
> Fix For: 2.7
>
>
> When a daemon node joins the cluster seems to switch to compatibility mode
> (allowing nodes without baseline support). It prevents baseline nodes from
> being restarted.
> Example:
> {code}
> Ignite ignite1 =
> IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
> "srv1");
> Ignite ignite2 =
> IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
> "srv2");
> ignite2.cluster().active(true);
> IgnitionEx.setClientMode(true);
> IgnitionEx.setDaemon(true);
> Ignite daemon =
> IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
> "daemon");
> IgnitionEx.setClientMode(false);
> IgnitionEx.setDaemon(false);
> ignite2.close();
> IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
> "srv2");
> {code}
> The attempt to restart ignite2 throws an exception:
> {code}
