Skew join and order by don't trigger reducer estimation
-------------------------------------------------------
Key: PIG-2652
URL: https://issues.apache.org/jira/browse/PIG-2652
Project: Pig
Issue Type: Bug
Reporter: Bill Graham
If neither PARALLEL, default parallel or {{mapred.reduce.tasks}} are set, the
number of reducers is not estimated based on input size for skew joins or order
by. Instead, these jobs get only 1 reducer.
