Hello,
Based on previous discussion with Thejas Nair about pig-0.8.1 unit test. I think jira should be opened for the following unit test(my research indicate the cause is HashMap does not guarantee ordering):
org.apache.pig.test.TestDataModel
org.apache.pig.test.TestLogToPhyCompiler
org.apache.pig.test.TestMRCompiler
org.apache.pig.test.TestMergeJoinOuter
org.apache.pig.test.TestNewPlanLogToPhyTranslationVisitor
org.apache.pig.test.TestPruneColumn
org.apache.pig.test.TestUnionOnSchema
org.apache.pig.test.TestPushDownForeachFlatten
org.apache.pig.test.TestTypeCheckingValidator
Actually, there are more three unit test failed, and I can not find the cause, please help to check the problems:(with sun java version "1.6.0_19" and Apache Ant(TM) version 1.8.2):

Some test failures are caused by ant 1.8 (See PIG-2172). Also we use
ArrayList instead of HashMap in Pig 0.9. Can you checkout from trunk
and try?

Hello Daniel,
what do you mean by "
checkout from trunk and try
"?

Hello Daniel Thejas,
I opened a jira for pig-0.8.1 unit test:https://issues.apache.org/jira/browse/PIG-2281
I put all my analysis information into description part. Not find good way to fix it. Any suggestion?
