-----------------------------------
Summary: Mapper example
Key: HADOOP-9697
URL: https://issues.apache.org/jira/browse/HADOOP-9697
Project: Hadoop Common
Issue Type: Bug
Reporter: DeepakVohra
Priority: Minor
The org.apache.hadoop.mapreduce
Class Mapper<KEYIN,VALUEIN,KEYOUT,VALUEOUT>
has an example with
public void map(Object key, Text value, Context context)
But, "Any type which is to be used as a key in the Hadoop Map-Reduce framework
should implement this interface."
org.apache.hadoop.io
Interface WritableComparable<T>
The example has Object for key type. Object doesn't implement
WritableComparable.
