The following example uses _log4j.properties_ as the input file:

```
hadoop fs -copyFromLocal /etc/hadoop/conf/log4j.properties
          s3a://testbucket/testdata
```

#### **4.2.2  Run the Spark shell:**

 *  Breaking: Rename `RecordedRequest.sequenceNumber` to `exchangeIndex` and introduce
    `connectionIndex` on that type. These properties may be useful when testing features like
    connection reuse.
