Jenkins Ref Link:
http://qa.sc.couchbase.com/job/centos_x64--29_01--create_view_all-P1/126/consoleFull

Test to Reproduce:
./testrunner -i myfile.ini get-cbcollect-info=True,get-logs=True, -t view.createdeleteview.CreateDeleteViewTests.rebalance_in_and_out_with_ddoc_ops,ddoc_ops=create,test_with_view=True,num_ddocs=3,num_views_per_ddoc=2,items=200000,sasl_buckets=1

Steps to Reproduce:
1. Setup a 4-node cluster
2. Create 1 default and 1 sasl bucket
3. Rebalance in 2 nodes
4. Start Rebalance
