Abstract

The invention provides a method for generating an object code of a Map / Reduce model, and data processing method and device. The method for generating the object code of the Map / Reduce model comprises the steps of: A, obtaining a user command; B, generating an intermediate code original drawing according to the user command; C, decomposing the intermediate code original drawing to obtain an intermediate code stage drawing corresponding to each execution stage in the Map / Reduce process; and D, translating the intermediate code stage drawing corresponding to each execution stage in the Map / Reduce process into the object code of each execution stage in the Map / Reduce process. Through the manner, the work difficulty of common developers is reduced, and the reusability of the code is improved to the benefit of transplanting and maintaining the code.

Description

【Technical field】 [0001] The invention relates to data processing technology, in particular to a method for generating an object code of a Map / Reduce model, a data processing method and a device. 【Background technique】 [0002] Distributed computing studies how to divide a problem that requires huge computing power into many small parts, then distribute these parts to many computers for processing, and finally combine these calculation results to get the final result. The Map / Reduce model proposed by Google is a distributed computing model. In the Map / Reduce model, through the Map stage, the tasks that can be executed in parallel are executed in parallel, and then through the Reduce stage, the intermediate results generated by the parallel execution tasks in the Map stage are combined to obtain the final result. In the existing technology, the distributed computing development platform of the Map / Reduce model that has been implemented is usually closely integrated with the ...
