> Need to output warnings when all data nodes left grid
> -----------------------------------------------------

> Key: IGNITE-552
> URL: https://issues.apache.org/jira/browse/IGNITE-552
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: sprint-2
> Reporter: Alexey Goncharuk
> Assignee: Sergey Kozlov
> Fix For: sprint-2
>
>
> We need to print out warning notifying the user when cache was created, but
> all data nodes have left the grid.
> To test the warning, do the following:
> # Start example node startup
> # Start random numbers streamer.
> # Kill node startup
> # Streamer should print warning.
