摘要：A new task scheduling algorithm based on Hadoop is proposed to optimize scheduling of resources problems under the Distributed cloud-computing platforms. The core idea of the algorithm is full reference to the current network conditions and treat it as an important reference for system task scheduling,with the bandwidth management ability ,SDN architecture allows us to allocate bandwidth according to a time slot strategy,then according to the operation completed sooner or later the time to decide whether the task assigned to the local node or low load of non-local node .In this way, we will not only ensure the locality of the task from a global perspective , but also assign tasks in an optimal way to efficiently. In the end, we do experiments based on the scheduler to verify the quality of scheduling algorithm.
