/**
 * Convert a task to a string key used in the (zk-->task) map. Note that the
 * string format here must match the one used in
 * {@link #toKey(DrillbitEndpoint)} to map a drillbit endpoint to string key.
 *
 * @param task
 *          the task tracked by the cluster controller
 * @return a string key for this object
 */
private String toKey(Task task) {
 return zkDriver.toKey(task.getHostName());
}

 * generated for hosts coming from YARN.
