Class ArtifactManager

Object
org.apache.spark.sql.artifact.ArtifactManager
All Implemented Interfaces:
org.apache.spark.internal.Logging
public class ArtifactManager extends Object implements org.apache.spark.internal.Logging
This class handles the storage of artifacts as well as preparing the artifacts for use.

Artifacts belonging to different SparkSessions are isolated from each other with the help of the sessionUUID.

Jars and classfile artifacts are stored under "jars", "classes" and "pyfiles" sub-directories respectively while other types of artifacts are stored under the root directory for that particular SparkSession.

param: session The object used to hold the Spark Connect session state.
