Date Fri, 05 Jun 2015 08:23:01 GMT
Lavkesh Lahngir created YARN-3770:
-------------------------------------

             Summary: SerializedException should also handle java.land.Error 
                 Key: YARN-3770
                 URL: https://issues.apache.org/jira/browse/YARN-3770
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Lavkesh Lahngir
            Assignee: Lavkesh Lahngir


IN SerializedExceptionPBImpl
{code}
    Class classType = null;
    if (YarnException.class.isAssignableFrom(realClass)) {
      classType = YarnException.class;
    } else if (IOException.class.isAssignableFrom(realClass)) {
      classType = IOException.class;
    } else if (RuntimeException.class.isAssignableFrom(realClass)) {
      classType = RuntimeException.class;
    } else {
      classType = Exception.class;
    }
    return instantiateException(realClass.asSubclass(classType), getMessage(),
      cause == null ? null : cause.deSerialize());
  }
{code}
if realClass is a subclass of java.lang.Error deSerialize() throws ClassCastException.
in the last else statement classType should be equal to Trowable.class instead of Exception.class.
