We use BigSql 4.0.1 for 1 year and a half.
Today when we want to plan a maintenance on one of our Hadoop cluster DataNode, we have running BigSql queries that can fail due to node beiing brought down.
I would like the engine to retry the request part on another worker node if the node is no longer reachable.
That way BigSql will be resilient to a single datanode failure.
Remember that datanode failure becomes a fairly normal event if you grow your cluster to 100 or 1000 nodes !!!
