Returns the last index of a Spark DataFrame. The Spark
<code>mapPartitionsWithIndex</code> function is used to iterate
through the last nonempty partition of the RDD to find the last record.

R interface to Apache Spark, a fast and general
engine for big data processing, see <https://spark.apache.org/>. This
package supports connecting to local and remote Apache Spark clusters,
provides a 'dplyr' compatible back-end, and provides an interface to
Spark's built-in machine learning algorithms.
