### **4.2 WordCount**

WordCount is a simple program that counts how often a word occurs in a text file. The code builds a dataset of (String, Int) pairs called counts, and saves the dataset to a file.

The following example submits WordCount code to the Scala shell. Select an input file for the Spark WordCount example. We can use any text file as input.

		index := s.getHashedSetIndex(object.ObjectName)
		objSetMap[index] = append(objSetMap[index], delObj{setIndex: index, origIndex: i, object: object})
	}

	// Invoke bulk delete on objects per set and save
	// the result of the delete operation
	var wg sync.WaitGroup
	var mu sync.Mutex
	wg.Add(len(objSetMap))
	for setIdx, objsGroup := range objSetMap {
		go func(set *erasureObjects, group []delObj) {

      val residentDuration = maxOf(0, nowMillis - receivedResponseMillis)
      return receivedAge + responseDuration + residentDuration
    }

    /**
     * Returns true if the request contains conditions that save the server from sending a response
     * that the client has locally. When a request is enqueued with its own conditions, the built-in
     * response cache won't be used.

### Download the files { #download-the-files }

Download the static files needed for the docs and put them on that `static/` directory.

You can probably right-click each link and select an option similar to "Save link as...".

**Swagger UI** uses the files:
