Subject [jira] [Resolved] (IGNITE-6973) Node restarts with enabled persistence lead to affinity assignment mismatch on different nodes.
Date Wed, 22 Nov 2017 10:20:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-6973?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Semen Boikov resolved IGNITE-6973.
----------------------------------
    Resolution: Fixed

There was a bug with deploymentId assigned to caches started during activation, fixed in master.

> Node restarts with enabled persistence lead to affinity assignment mismatch on different
nodes.

>             Project: Ignite
>          Issue Type: Bug
>    Affects Versions: 2.3
>            Reporter: Alexei Scherbakov
>            Assignee: Semen Boikov
>             Fix For: 2.4
>
>
> Most probably this is caused by deploymentId reassign after grid restart.
> All nodes must have same deploymentId in such case.
