Class MLContextProxy

java.lang.Object

org.apache.sysds.utils.MLContextProxy

public class MLContextProxy
extends Object

The purpose of this proxy is to shield systemds internals from direct access to MLContext which would try to load spark libraries and hence fail if these are not available. This indirection is much more efficient than catching NoClassDefFoundErrors for every access to MLContext (e.g., on each recompile).
