Object Storage Service (OBS)

OBS stores the following user data:

  • MRS job input data, such as user programs and data files
  • MRS job output data, such as result files and log files of jobs

In MRS clusters, HDFS, Hive, MapReduce, YARN, Spark, Flume, and Loader can import or export data from OBS.

MRS uses the parallel file system of OBS to provide services.
