Review Comment:
@eolivelli, all locations including created by this loop and get from
`partitionLocationInfo` should destroy the writers via the following code:
```
var location = partitionLocationInfo.getPrimaryLocation(shuffleKey,
requestPrimaryLocs.get(ind).getUniqueId)
if (location == null) {
...
} else {
primaryLocs.add(location)
}
```
