GEOMESA-327 fixing Try around hadoop initialization

FYI, for comprehensions are an option for things like this:
```
val status: Try[T] = for { 
  jobClient <- Try(new JobClient(GeoMesaBasePage.getHdfsConfiguration))
 clusterStatus <- Try(jobClient.getClusterStatus)
} yield clusterStatus
handleStatus(status)

def handleStatus(t: Try[T]) = {....
```
Here it isn't strictly needed.
