------------------------------------
Affects Version/s: 2.5
> ZookeeperClusterNode class instances sneak into BaselineTopology when
> non-empty user attributes are defined
> -----------------------------------------------------------------------------------------------------------
>
> Key: IGNITE-8857
> URL: https://issues.apache.org/jira/browse/IGNITE-8857
> Project: Ignite
> Issue Type: Bug
> Components: zookeeper
> Affects Versions: 2.5
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Major
> Fix For: 2.7
>
>
> When persistence-enabled cluster is activated for the first time, it saves
> information about cluster nodes into BaselineTopology, including user
> attributes.
> It turned out that in case of cluster started with ZookeeperDiscoverySpi on
> first activation instances of ZookeeperClusterNode are persisted to disk
> within BaselineTopology.
> After that the same nodes cannot be switched to TcpDiscoverySpi without
> having ignite-zookeeper.jar on classpath, an attempt to start cluster results
> in the following exception:
> {code}
> org.apache.ignite.IgniteCheckedException: Failed to start processor:
> GridProcessorAdapter []
