Embodiment Construction
[0018] Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a method for determining the location of a data node, which can be applied to a system including a management node, multiple data nodes, and multiple switching devices, such as a Hadoop system. Wherein, the management node can also be called a name node, which is responsible for managing the name space of the Hadoop system and controlling the access of external users. The switching device may be a core switching device (such as a core switch or a core router) or a rack switching device (such as a rack switch).
[0019] by figure 2 It is a schematic diagram of an application scenario of an embodiment of the present invention. The Hadoop system includes a core switching device, a rack switching device 1, a rack switching device 2, a data node 1, a data node 2, a data node 3, a data node 4, and a data node 5. data node6. The rack switching device is connected to each data n...
