I am using the old api and my Reducer class has the following signature (only
relevant parts shown):
import org.apache.hadoop.mapred.MapReduceBase;
import org.apache.hadoop.mapred.OutputCollector;
import org.apache.hadoop.mapred.Reducer;
import org.apache.hadoop.mapred.Reporter;
public class FlagDropComparisionReducer extends MapReduceBase
implements Reducer<Text, Text, Text, Text> {
public void reduce(Text key, Iterator<Text> values,
OutputCollector<Text, Text> output, Reporter reporter) {
......
String result = some code here to compute result using key and value
Use HTTP Client to POST "result" to server
}
}
I don't want to write the output of reducer to HDFS ie no
"output.collect(key, somevalue). Is there a way for me to do this using the
old api? Note: I must have a reducer because I am doing some calculation
here (not shown).
Suggestions? Thanks.
