Hello Alexey, Thanks for the valuable information, i hare tried executing a list of dependent tasks using a DAG using session.setAttribute("COMPLETE",true), and it is working fine as long as there are three nodes, cause there are 3 or less parallel tasks to execute.
But when i run the same code of dependent tasks on a single node, then it stops its execution after execution of few tasks in some time . There are no exception as such. could u please let me know where i could have gone wrong. Note : should i have to use waitForAttribute for the same if so could u please guide me the usage of wiatForAttribute for completion of three parallel tasks at every step. thanks and regards, chandrika -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
