Hadoop capacity scheduler algorithms can not meet the different requirements of different users on service quality of cloud computing.Therefore, this paper proposed the SLA-Capacity scheduler algorithm which on the basis of the existing capacity scheduler algorithm, introduce the concept of SLA, design weighted scheduler algorithm based Qos (Quality of Service) constraints.Due to each user's jobs with different QoS preference, According to the part of QoS parameters to calculate the weight value which be used to decide the job scheduler order, so as to ensure that the user's service quality, improve user satisfaction.Experiments on Hadoop show that improved algorithm can effectively reduce the waiting time for user operation, improve the overall operating efficiency.
