Actually you don't even need to add a field to the class since you never
use `cause`. Then you can rewrite the second constructor to look like:
```
def this(
bmAddress: BlockManagerId,
shuffleId: Int,
mapId: Int,
reduceId: Int,
cause: Throwable) {
this(bmAddress, shuffleId, mapId, reduceId, cause.getMessage)
}
```
