Enclosing class:

InJvmContainerExecutor

public static class InJvmContainerExecutor.SystemExitAllowSecurityManager
extends SecurityManager

An implementation of the SecurityManager which can be used to intercept System.exit. This implementation will simply throw an exception when such call is made essentially making such call ineffective. It is used by this class to intercept System.exit calls made by some implementations of YARN containers (e.g., Tez's DAGAppMaster). Since this container executor will use the same JVM its running in to start those containers any System.exit call will shut down the entire cluster. Using such SecurityManager would allow such calls to be intercepted by catching SystemExitException.
