Tks! I applyed the patch from the issue.And the NPE was fixed. But another problems happen:
As the issue says: Steps to reproduce: Ignite server region1 (with persistence) region2 (without persistence) client cache1a from region1 – with custom affinity cache2a fom region2 – with custom affinity !!! set backups=2(diff from the issule) 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. Don't restart client.Wait for the client to reconnect. Then the cache2a basckup will be 0 not 2! It looks like client reconnect did not carry cacheconfiguration(backups=2) but just use cacheName -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
