    // Wait until scan finishes before closing cluster.  This is only necessary
    // when running the async scan example from the command line (which closes the
    // cluster after control is relinquished by this example).
    // The async scan will continue to run after cluster close if the scan was
    // initiated before cluster close.  The problem is cluster close shuts down
    // cluster tending immediately so any data partition migrations will not be
    // received by the client when performing the scan.
