Distributed system and coordinated scheduling method for job tasks of distributed system

The invention discloses a distributed system and a job task coordinated scheduling method thereof, a management end writes a job task and an operation command into a message queue, each distributed consumption end acquires the job task and the operation command by subscribing the message queue, and scrambles for a task lock from a zookeeper scheduling server, so that the job task and the operation command are scheduled. And implementing operation by the consumption end which obtains the task lock first. And after monitoring that the job task is in a starting state, each distributed consumption end sequentially queries the state of each flow node of the job task, and when the queried state of the flow node is'unfinished ', the flow node is started as a currently executed flow node, and an unexecuted fragment node under the flow node is acquired and executed. According to the method, the coordinated scheduling of the job tasks is realized, the execution states on a plurality of consumption ends are mutually per
