> Currently, when a query comes, all active nodes are assumed to be participants in the query execution and therefore the query required resources is calculated accordingly. However, this isn't the case when a dataset is partitioned in a node group that doesn't include all nodes (e.g. the metadata datasets). This will result in an overestimation in resources required and will cause the query to fail with (HYR0009: Job requirement exceeds capacity) when one of the none participating nodes leaves the cluster when it shouldn't fail.
