Explore writng a specialized summarizer for bulk ingest

[keith-turner]

To debug a recent bulk ingest test I wrote the following summarizer. This summarizer counted the number of times each UUID was seen. I used to count the number of entries each map reduce job had created.

package test.ci;

import org.apache.accumulo.core.client.summary.CountingSummarizer;

public class CiUuidSummarizer extends CountingSummarizer<String>{

  @Override
  protected Converter<String> converter() {
    return (k,v,c) -> c.accept(v.toString().split(":")[0]);
  }

}
