Hi,
Is there any detailed documentation on the org.apache.hadoop.contrib.utils.join package ? I have a simple Join task consisting of 2 input datasets. Each contains tab-separated records. Set1: Record format = field1\tfield2\tfield3\tfield4\tfield5 Set2: Record format = field1\tfield2\tfield3 Join criterion: Set1.field1 = Set2.field1 Output: Set2.field2\tSet1.field2\tSet1.field3\tSet1.field4 The org.apache.hadoop.contrib.utils.join package contains DataJoinMapperBase and DataJoinReducerBase abstract classes, and a TaggedMapOutput class which should be the base class for the mapper output values. But there aren't any examples showing how these classes should be used to implement inner or outer joins in a generic manner. If anybody has used this package and would like to share their experience, please let me know. Thanks, Rahul Sood [EMAIL PROTECTED]
