Query dropped when node goes down

When query is running and a node goes down e.g. node-4 then the query will get dropped. Is it possible to overcome this, like running query should not get dropped?

    In Eon mode, when a query participating node is down, the existing query execution must be canceled. However, if the query is still eligible for retry, it will happen and session will refresh its shard participation, and rerun the query. This works similar to the Enterprise mode when there is a node down.
