Class AccumuloFileOutputFormat

java.lang.Object
  org.apache.hadoop.mapreduce.OutputFormat<K,V>
      org.apache.hadoop.mapreduce.lib.output.FileOutputFormat<Key,Value>
          org.apache.accumulo.core.client.mapreduce.AccumuloFileOutputFormat

public class AccumuloFileOutputFormat
extends org.apache.hadoop.mapreduce.lib.output.FileOutputFormat<Key,Value>

This class allows MapReduce jobs to use the Accumulo data file format for output of data The user must specify the output path that does not exist following via static method calls to this class: AccumuloFileOutputFormat.setOutputPath(job, outputDirectory) Other methods from FileOutputFormat to configure options are ignored Compression is using the DefaultCodec and is always on
