-------------------------------------

             Summary: SerializedException should also try to instantiate 
internal exception with the default constructor
                 Key: YARN-3745
                 URL: https://issues.apache.org/jira/browse/YARN-3745
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Lavkesh Lahngir
            Assignee: Lavkesh Lahngir


While deserialising a SerializedException it tries to create internal exception 
in instantiateException() with cn = cls.getConstructor(String.class).
if cls does not has a constructor with String parameter it throws Nosuchmethod 
error. 
for example ClosedChannelException class.  
We should also try to instantiate exception with default constructor so that 
inner exception can to propagated.
