def test_run_queries_cbas_shutdown(self):
'''
Description: This test the ongoing queries while cbas node goes down.
Steps:
1. Add first cbas node.
2. Start rebalance, wait for rebalance complete.
3. Create bucket, datasets, connect bucket. Data ingestion should start.
4. Add another cbas node, rebalance.
5. Start concurrent queries on first cbas node.
6. Second cbas node added in step 4 should be able to serve queries.

Description: This test will add the second cbas node then start rebalance and cancel rebalance
before rebalance completes.
Steps:
1. Add first cbas node.
2. Start rebalance, wait for rebalance complete.
3. Create bucket, datasets, connect bucket. Data ingestion should start.
4. Add another cbas node, rebalance.
5. Stop Couchbase service for Node1 added in step 1. Failover the node and rebalance.
6. Second cbas node added in step 4 should be able to serve queries.
