Subject [jira] [Created] (IGNITE-9129) P2P class deployment is failed when using ZK discovery
Date Mon, 30 Jul 2018 16:15:00 GMT
Pavel Kovalenko created IGNITE-9129:

             Summary: P2P class deployment is failed when using ZK discovery
                 Key: IGNITE-9129
                 URL: https://issues.apache.org/jira/browse/IGNITE-9129
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.6, 2.5
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko
             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.
