             Summary: TestEmptyInputDir unit test - hadoop version detection 
logic is brittle
                 Key: PIG-3024
                 URL: https://issues.apache.org/jira/browse/PIG-3024
             Project: Pig
          Issue Type: Bug
          Components: build
    Affects Versions: 0.10.0
            Reporter: John Gordon
            Assignee: John Gordon
            Priority: Minor


When the hadoop core version dependency is changed, TestEmptyInputDir almost 
always fails as coded.  The issue is that it assumes all hadoop versions  have 
MAPREDUCE-3606 fixed except two.  It is more resilient to check families of 
releases for the fix than to check the release number directly.  Right now, it 
is safer to assume the bug is present unless the release is one of those with 
the fix than it is to assume all releases have the fix except for two.
