Embodiment Construction
[0037] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] Such as figure 1 As shown, the Hadoop distributed cluster environment in this embodiment has 3 servers, which constitute 3 nodes, including a master node Master for issuing orders and distributing tasks, and 2 sub-node slaves for receiving tasks distributed by the master node and according to the master node. Node Master requests to process running tasks, and all nodes are connected through high-speed Ethernet. The master node Master starts the entire cluster environment according to the user's application request. The slave node slave and the master node Master are the main body of the Hadoop distributed cluster environment parallel system, responsible for the processing and operation of the entire Hadoop distributed cluster. Such as figure 2 As shown, in this embodiment: 1) receive data to be processed according to u...
