EMR supports Spark 3.x and 2.x. The software environment information is as follows:
By default, Spark is installed on a master node.
After logging in, run the su hadoop command to switch to the hadoop user.
The Spark software path is /usr/local/service/spark.
The relevant logs are stored in /data/emr.
The above is mainly about how to access COS by using Spark. For more information, see the community documentation.
