This section describes the relationships between MRS and other services.
MRS clusters are created in the subnets of a VPC. VPCs provide secure, isolated, logical network environments for MRS clusters.
OBS stores the following user data:
In MRS clusters, the HDFS, Hive, MapReduce, Yarn, Spark, Flume, and Loader modules can import or export data from OBS.
Each node in an MRS cluster is an ECS.
IAM provides authentication for MRS.
CTS provides operation records, including requests for operating MRS resources and the request results, for users to query, audit, and trace back the recorded problems.
