>                 URL: https://issues.apache.org/jira/browse/IGNITE-4111
>             Project: Ignite
>          Issue Type: Bug
>          Components: general
>            Reporter: Semen Boikov
>            Assignee: Amelchev Nikita
>            Priority: Minor
>             Fix For: 2.8
>         Attachments: test onFirstMessage hang.log
> Currently this scenario is possible:
> - joining node sent join request and waits for TcpDiscoveryNodeAddFinishedMessage inside
> - others nodes already see this node and can send messages to it (for example try to
run compute job on this node)
> - joining node can not receive message: TcpCommunicationSpi will hang inside 'onFirstMessage'
on 'getSpiContext' call, so sending node will get error trying to establish connection
> Possible fix: if in onFirstMessage() spi context is not available, then TcpCommunicationSpi
 should send special response which indicates that this node is not ready yet, and sender
should retry after some time.
> Also need check internal code for places where message can be unnecessarily sent to node:
one such place is GridCachePartitionExchangeManager.refreshPartitions - message is sent to
all known nodes, but here we can filter by node order / finished exchage version.
