> Whats the intent of recommissioning? I don't super get it normally decommissioning means the worker is going away is this for the situation where (for example) planned maintance is cancelled? @holdenk Thanks for looking at this. We're doing manually scaling up and down workers based on spark metric. Manually means we're using master rest api to kill workers. Let's say we have 10 nodes to be decommissioned. 9 nodes finished quickly, but the last one took long as it might have more shuffle data to migrate or some long tail tasks still running. So we want to cancel the long tail node decommission to avoid shuffle data loss or task failure as during decommission it can't run new tasks it's waste of resource. -- This is an automated message from the Apache Git Service.
