Dealing with this separately in two code paths is prone to errors in the
future. Can you make the `compute(time) match { ... }` return into a variable
and use that later. Something like this.
```
val rddOption = compute(time) match {
// no setCallSite inside this
}
setCallSite(prevCallSite) // only one instance of setCallSite, common to
both code paths.
return rddOption
```
And while on that, can you also add `return` at other code paths in this
function. That is, the `None` in lines 332 and 335 in this commit?
