PSYNC in RC-4 build.

[Sairam M P]

Replication version 2 - That's a great thing in redis-RC-4.

Was trying to achieve the partial sync on failover, but for me it does full sync in all the cases with RC-4 build. Any configuration to be enabled to get this working..? 

In the master server i see : 

master_replid:2d14472061507c19634144097ddef5107a9e4a20 /

master_replid2:c41f808baffcc023cb67e91b84ec84ca82629e09

But in slave its : 

master_replid:2d14472061507c19634144097ddef5107a9e4a20

master_replid2:0000000000000000000000000000000000000000

Could this be the reason for psync failure ??
