Review Comment:
The way `updateMetrics` is written is a little annoying. While we're at it,
would it be any clearer to revise `updateMetrics` to the following structure:
```scala
if (isActive) {
offlinePartitionCount = controllerContext.offlinePartitionCount
...
} else {
offlinePartitionCount = 0
...
}
```
