Managing Resources

Updated on 2022-02-22 GMT+08:00

You can upload custom code or text files as resources on Manage Resource and schedule them when running nodes. Nodes that can invoke resources include DLI Spark, MRS Spark, MRS MapReduce, and DLI Flink Job.

After creating a resource, configure the file associated with the resource. Resources can be directly referenced in jobs. When the resource file is changed, you only need to change the resource reference location. You do not need to modify the job configuration. For details about resource usage examples, see Developing a Spark Job.
