Details

    Description

      Steps:
      1. Create a 2 node cluster:

      +----------------+----------+--------------+
      		 
      | Nodes          | Services | Status       |
      		 
      +----------------+----------+--------------+
      		 
      | 172.23.105.220 | [u'kv']  | Cluster node |
      		 
      | 172.23.105.221 | None     | <--- IN ---  |
      		 
      +----------------+----------+--------------+

      2. Create default bucket with replicas=1
      3. Load 50k items with durability=MAJORITY
      4. Add 2 more nodes to the cluster and rebalance out 1 node and check bucket replica to 2. Then hit rebalance.

      +----------------+----------+--------------+
      		 
      | Nodes          | Services | Status       |
      		 
      +----------------+----------+--------------+
      		 
      | 172.23.105.220 | [u'kv']  | Cluster node |
      		 
      | 172.23.105.221 | [u'kv']  | --- OUT ---> |
      		 
      | 172.23.105.223 | None     | <--- IN ---  |
      		 
      | 172.23.105.225 | None     | <--- IN ---  |
      		 
      +----------------+----------+--------------+

      5. While 4 is running load 50k more documents with durability=MAJORITY
      6. Rebalance failed
