All Implemented Interfaces:

org.apache.tez.runtime.api.LogicalOutput, org.apache.tez.runtime.api.Output

public class OnFileUnorderedPartitionedKVOutput
extends OnFileSortedOutput

OnFileUnorderedPartitionedKVOutput is a LogicalOutput which can be used to write Key-Value pairs. The key-value pairs are written to the correct partition based on the configured Partitioner. This currently acts as a usable placeholder for writing unordered output (the data is sorted, which should be functionally correct since there's no guarantees on order without a sort). TEZ-661 to add a proper implementation.
