Review Comment:
Are we changing the response string, I am not sure about the compatibility
here.
The above javadoc says
```
String value does not include exception type, just exit code and message.
```
We shouldn't make prod level API changes for MiniDFSCluster

> When the MiniDFSClsuter detects that an exception caused an exit, it should
> include that exception as the cause for the AssertionError that it throws.
> The current AssertError simply reports the message "Test resulted in an
> unexpected exit" and provides a stack trace to the location of the check for
> an exit exception.
