Hi, There is no way to get a task state from every node. The state of a particular task can be taken only on the node that initiated its execution and only if the task is still running. When a task is completed you have to store its result somewhere and pass to the client later.
In general if the task is still running you should execute IgniteCompute.activeTaskFutures on the originating node and check if it’s still in progress or not.
