摘要： A resource request is sent from a user to a resource controller. The resource controller is resident on a node of a distributed computing platform comprising a plurality of nodes configured to collectively execute at least one application program. A quota pool associated with the resource controller is searched for a matching resource quota for the user to inherit. The resource quota is assigned to the user when a matching resource quota for the user to inherit is found in the quota pool. The resource request is forwarded to a resource scheduler that globally manages resources for the distributed computing platform, when a matching resource quota for the user to inherit is not found in the quota pool.

摘要： It is decided whether to increase a total amount of storage in a pool of Hadoop storage and whether to increase a total amount of processing in a pool of Hadoop processing. If it is decided to increase the total amount of storage and not increase the total amount of processing, the total amount of storage is increased without increasing processing. If it is decided to not increase the total amount of storage and increase the total amount of processing, the total amount of processing is increased without increasing storage. In response to receiving a request to perform a process on a set of data, processing is allocated from the pool of processing and storage is allocated from the pool of storage where the allocated processing and storage are used to perform the process on the set of data.

摘要： Embodiments of the present invention relate to method and apparatus for system problem diagnosis and recovery. According to embodiments of the present invention, problem symptom information in a system can be automatically monitored and collected BY a monitoring apparatus (or referred as to “agent”) deployed at the system side. Upon after receiving such information, the diagnosis apparatus, for example, may automatically determine a root cause of the problem by querying a backend knowledge repository, and possibly generate an executable software package for recovering the problem. If the diagnosis apparatus determines that the currently available information is insufficient to determine a creditable enough root cause and/or is insufficient to generate the software package for recovering the problem, the diagnosis apparatus may interactively control the monitoring apparatus to collect desired additional information. In this way, the efficiency and accuracy of problem diagnosis and recovery may be improved.

摘要： A data classification system is associated with a hybrid cloud comprising at least one private cloud and at least one public cloud. The data classification system comprises a data set classification model classifying data sets, a cloud classification model classifying the private and public clouds of the hybrid cloud, and mapping policies each specifying a particular mapping between one or more classes of the data set classification model and one or more classes of the cloud classification model. The data classification system classifies a received data set using the data set classification model, and determines for the received data set at least one cloud of the hybrid cloud to which the received data set should be directed for further processing based at least in part on a result of the classification of the received data set, the cloud classification model and a selected one of the mapping policies.

摘要： The present invention relates to a method and apparatus for data management in multi-tenant distributive environment. According to the embodiments of the present invention, a tenant-specific virtual metadata server may be created and registered with a task manager in a job processing system. The virtual metadata server provides a tenant-specific logical file system namespace. Any access to tenant data will be performed via the virtual metadata server. In other words, such virtual metadata server acts as an interface between a tenant terminal and an entity file system. In this way, it may effectively realize isolation of tenant data and enhance data security. Moreover, by using a virtual metadata server rather than physically isolating user data, the embodiments of the present invention may guarantee the efficiency of data sharing while improving the data security.
