Abstract

The invention discloses a Hadoop cluster calling method and device. The method comprises the following steps: after an application program is started, initializing a Hadoop API, and describing a virtual Hadoop cluster by adopting the initialized API according to a default value; reading a configuration file, uploaded by a user, of a to-be-called Hadoop cluster; updating the default value by adopting the configuration file so as to obtain a new value; re-initializing the Hadoop API, and describing a real Hadoop cluster by adopting the re-initialized API according to the new value; and calling the real Hadoop cluster according to information of the real Hadoop cluster. The method is capable of improving the flexibility during the calling of Hadoop clusters so as to dynamically call the Hadoop clusters, and the developers do not need to well understand the installation details of the Hadoop clusters.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for invoking a hadoop cluster. Background technique [0002] Hadoop is a distributed system infrastructure. Users can develop distributed programs without knowing the underlying details of the distribution, and make full use of the power of the cluster for high-speed computing and storage. When developing some applications based on hadoop clusters, developers generally use two methods. The first way is to embed the configuration file of the cluster into the code of the application program, and then call the cluster service through the default processing mode of the hadoop application programming interface (Application Programming Interface, API). Another method requires the developer to pass the parameters required to call the cluster service to the corresponding API. However, the first method is not flexible enough, and the second method requires develop...
