    Description

      Steps:

      1. Create a 15 node cluster
      2. Create required buckets and collections.
      3. Create 1000000 items sequentially
      4. Create 1000000 random keys
      5. Update 2000000 random keys to create 50 percent fragmentation
      6. Rebalance in with Loading of docs
      7. Rebalance Out with Loading of docs
      8. Rebalance In_Out with Loading of docs
      9. Swap with Loading of docs
      10. Failover a node and RebalanceOut that node with loading in parallel
      11. Failover a node and FullRecovery that node
      12. Failover a node and DeltaRecovery that node with loading in parallel
      13. Updating the bucket replica to 2
      14. Updating the bucket replica to 1
      15. Flush the bucket and start the entire process again
      16. Repeat all steps from step 3
      17. Flush failed in the 2nd iteration.

      Flushing "GleamBook" failed with error:
      		 
      {error,{flush_wait_failed,['ns_1@172.23.121.115','ns_1@172.23.121.129',
      		 
      'ns_1@172.23.121.130','ns_1@172.23.121.141'],
      		 
      []}}
