Anton Vinogradov commented on IGNITE-2864:
------------------------------------------

Eventually I've added system property IGNITE_LOCAL_STORE_KEEPS_PRIMARY_ONLY and 
set it false by default. It means that new behavior will be active by default.
Also I added more tests for old and new behavior.
In case user will try to combine nodes with versions "before" and "after" fix 
with configured local store he will gain warning:
"Since Ignite 1.5.15 Local Store keeps primary and backup partitions. To keep 
primary partitions only please set system property 
IGNITE_LOCAL_STORE_KEEPS_PRIMARY_ONLY  to 'true'."
  

> Need update local store from primary and backups

>
> Now cache local store is updated only from primary nodes, this means that 
> data can be lost if primary node is not re-started after crash. Need fix it 
> and update store from primaries and backups if store is local (for both tx 
> and atomic caches).
> This test should work:
> - cache with 1 backup, two server nodes
> - execute cache put for key K
> - stop both nodes
> - restart only node which was backup for K
> - load data from local sore, update for K should be restored
