Target customers: all users. Features released: DataWorks allows you to create EMR nodes such as EMR Hive, EMR MR, EMR Presto, and EMR Spark SQL nodes based on EMR data lake clusters. You can use different types of EMR nodes to implement the features such as configuration of an EMR workflow, scheduling of nodes in a workflow, or metadata management in a workflow. These features help you efficiently generate data by using EMR. After an EMR job for an EMR data lake cluster is developed, you can manage the metadata for the job of the cluster, monitor O&M operations on nodes created for the cluster, and monitor the data quality of the cluster in DataWorks to ensure that data is normally generated.
