The previous codes are:
```scala
1 try {
2 blockManager.dataSerializeStream(blockId, outputStream, values)
3 outputStream.close()
4 } catch {
5 case e: Throwable => {
6 outputStream.close()
7 if(file.exists()) {
8 file.delete()
9 }
10 throw e
11 }
12 }
```
My concern is if L6 outputStream.close() throws an exception,
`if(file.exists()) { file.delete() }` won't be executed. So I changed to the
nested `try`s.
