> Summary:
> This issue is seen when we have two caches mapped to two different regions (one with persistence and one without persistence)
> The client-side config should have the cache definitions
> The server-side config should have the data regions only
> Affinity should be defined on the cache without persistence
> We need to populate the data into both the caches and then restart the server and clients
> The issue will be seen when the client reconnects.
> Workaround:
> Add the cache configurations (for the caches without persistence) to the server-side config.
> Steps to reproduce:
> Ignite server
> - region1 (with persistence)
> - region2 (without persistence)
> client
> - cache1a from region1 – with custom affinity
> - cache2a fom region2 – with custom affinity
> 1. Populate data in both cache1a and cache2a.
> 2. Restart ignite server. It knows about cache1a from the persistent store. It doesn’t know about cache2a.
> 3. Restart client. When it connects to ignite, the server sees a nullpointer
