From source file org.apache.jena.hadoop.rdf.io.output.writers.AbstractBatchedNodeTupleWriter.java
/**
* An abstract implementation of a record writer that writes records in batches.
* <p>
* It is important to note that the writer will write output periodically once
* sufficient tuples have been gathered. If there is an incomplete batch when
* the {@link #close(TaskAttemptContext)} method is called then the final batch
