Test to Reproduce:
./testrunner -i myfile.ini -t view.createdeleteview.CreateDeleteViewTests.ddoc_ops_during_failover,ddoc_ops=delete,test_with_view=True,num_ddocs=2,num_views_per_ddoc=3,items=200000,nodes_out=2,replicas=2,sasl_buckets=2,sasl_bucket_priority=low:high
./testrunner -i myfile.ini get-cbcollect-info=True,get-logs=True, -t view.createdeleteview.CreateDeleteViewTests.ddoc_ops_during_failover,ddoc_ops=update,test_with_view=True,num_ddocs=2,num_views_per_ddoc=2,items=200000,nodes_out=1,sasl_buckets=1,standard_buckets=1
Note: Test is reproducible once in 2-3 times

Steps to Reproduce:
1. Setup 4-node cluster
2. Create buckets 1 default, 2 sasl(low and high priority)
3. Load documents 200000
4. Create Views
5. Start ddoc operations parallel with node failover
6. Run View Queries on all buckets

Missing Items: Attached is test log and query result.
