Class REEFUncaughtExceptionHandler

java.lang.Object

org.apache.reef.runtime.common.launch.REEFUncaughtExceptionHandler

All Implemented Interfaces:

Thread.UncaughtExceptionHandler

public final class REEFUncaughtExceptionHandler
extends Object
implements Thread.UncaughtExceptionHandler

This is used as the Exception handler for REEF client processes (Driver, Evaluator).

It catches all exceptions and sends them to the controlling process. For Evaluators, that is the Driver. For the Driver, that is the Client.

After sending the exception, this shuts down the JVM, as this JVM is then officially dead.
