HUAWEI CLOUD big data processing platform usually uses the tags of computing resources and storage resources together to realize the support of heterogeneous devices in the Hadoop cluster.The following description of the effects of these two scheduling strategies, which one is wrong?
A. hrough the computing resource label, Spark jobs can be scheduled to run on large memory nodes, while MR job scheduling runs on standard memory nodes
B. hrough the storage resource label, online application data can be stored in the HDFS directory of the SAS disk node, and offline application data can be stored in the HDFS directory corresponding to the SATA disk node
C. he tags of computing resources and storage resources are usually used together to allow designated applications to access computing and data resources across nodes
D. omputing resource label scheduling is a feature of Yarm, and storage resource scheduling is a feature of HDFS
