Subject [jira] [Created] (PIG-3725) Bunch of e2e tests fail on Hadoop 2 in some setting
Date Mon, 27 Jan 2014 05:50:38 GMT
Daniel Dai created PIG-3725:
-------------------------------

             Summary: Bunch of e2e tests fail on Hadoop 2 in some setting
                 Key: PIG-3725
                 URL: https://issues.apache.org/jira/browse/PIG-3725
             Project: Pig
          Issue Type: Bug
          Components: impl
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.12.1, 0.13.0


Here is a list of failed tests: Join_6, MergeJoin_5, Join_8, Join_7, MergeJoin_2, MergeJoin_3,
MergeJoin_8, MergeJoin_1, MultiQuery_14, MergeJoin_4, MergeJoin_9, MergeJoin_6, MergeJoin_7.

In these tests, Pig need to read a local file distributed by distribute cache. However, Pig
try to read hdfs instead. Here is the stack:
