Hi All,
I am using pig-0.10.0 with hadoop-1.1.1, and following tests failed with the information:

Testcase: testSkewedJoin took 45.001 sec
        FAILED
expected:<0> but was:<2>
junit.framework.AssertionFailedError: expected:<0> but was:<2>
        at org.apache.pig.test.TestEmptyInputDir.testSkewedJoin(TestEmptyInputDir.java:86)

Testcase: testMergeJoin took 34.742 sec
        FAILED
expected:<0> but was:<2>
junit.framework.AssertionFailedError: expected:<0> but was:<2>
        at org.apache.pig.test.TestEmptyInputDir.testMergeJoin(TestEmptyInputDir.java:119)

Testcase: testFRJoin took 28.432 sec
        FAILED
expected:<0> but was:<2>
junit.framework.AssertionFailedError: expected:<0> but was:<2>
        at org.apache.pig.test.TestEmptyInputDir.testFRJoin(TestEmptyInputDir.java:153)

Question:
The code is following, this shows that when using hadoop-1.0.*, the assert code will not be run. I think the situation should be the same with hadoop-1.1.1. Is this correct? As from job.xml, I found the correct ">mapred.map.tasks" is 0 but not 2.
            // This assert fails on 205 due to MAPREDUCE-3606
            if (!Util.isHadoop205()&&!Util.isHadoop1_0())
                assertEquals(0, js.getNumberMaps());

Hi Fangfang,

This is fixed by PIG-3099:
https://issues.apache.org/jira/browse/PIG-3099

Please try Pig-0.10.1 or Pig-0.11.

Thanks,
Cheolsoo
