    Description

      Steps to Reproduce

      1. Create a 3 node cluster

      +----------------+----------+--------------+
      		 
      | Nodes          | Services | Status       |
      		 
      +----------------+----------+--------------+
      		 
      | 10.112.180.101 | [u'kv']  | Cluster node |
      		 
      | 10.112.180.102 | None     | <--- IN ---  |
      		 
      | 10.112.180.103 | None     | <--- IN ---  |
      		 
      +----------------+----------+--------------+

      2. Add a default bucket with replicas=0
      3. Load 50k items to the bucket with durability=MAJORITY
      Bucket statistics:

      +---------+---------+----------+-----+-------+------------+-----------+-----------+
      		 
      | Bucket  | Type    | Replicas | TTL | Items | RAM Quota  | RAM Used  | Disk Used |
      		 
      +---------+---------+----------+-----+-------+------------+-----------+-----------+
      		 
      | default | membase | 0        | 0   | 50000 | 6716129280 | 120314264 | 177073826 |
      		 
      +---------+---------+----------+-----+-------+------------+-----------+-----------+

      4. Rebalance out 1 node and start data loading(update, create, delete items) in a separate thread

      +----------------+----------+--------------+
      		 
      | Nodes          | Services | Status       |
      		 
      +----------------+----------+--------------+
      		 
      | 10.112.180.101 | [u'kv']  | Cluster node |
      		 
      | 10.112.180.103 | [u'kv']  | --- OUT ---> |
      		 
      | 10.112.180.102 | [u'kv']  | Cluster node |
      		 
      +----------------+----------+--------------+
