> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.5, 2.6
> Reporter: Pavel Kovalenko
> Assignee: Pavel Kovalenko
> Priority: Critical
> Fix For: 2.7
>
>
> In case of using Zookeeper Discovery, cluster node which joins to a cluster
> receives information that some user-classes have been already deployed but
> doesn't exist in the local classpath. In this case, the node tries to request
> for these classes from nodes that contain it, but do it synchronously during
> Zookeeper Discovery starting and gets NullPointer when first topology
> snapshot has not initialized yet.
> We should request for user-classes asynchronously and only after the first
> topology has initialized.
