--------------------------------------
I also think 3 is better long term as we add more/different tests in the future.
> Webhcat e2e tests TestMapReduce_1 and TestHeartbeat_2 require changes for
> Hadoop 2

> Key: HIVE-5115
> URL: https://issues.apache.org/jira/browse/HIVE-5115
> Project: Hive
> Issue Type: Bug
> Components: Tests
> Affects Versions: 0.12.0
> Reporter: Deepesh Khandelwal
> Assignee: Deepesh Khandelwal
>
> In the webhcat e2e testsuite we have two MR job submission tests
> TestMapReduce_1 (in jobsubmission.conf) runs the hadoop "wordcount" example.
> Intention of this one is to test MR job submission using WebHCat.
> TestHeartbeat_2 (in jobsubmission2.conf) runs the hadoop "sleep" example.
> Intention of this one is to test a long running (>10min) WebHCat MR job, see
> HIVE-4808.
> In Hadoop 1, both of these example MR applications are packaged in
> hadoop-examples.jar
> In Hadoop 2, "sleep" job is bundled in hadoop-mapreduce-client-jobclient.jar
> and "wordcount" is bundled in hadoop-mapreduce-examples.jar
> Currently the webhcat tests assume that both these MR applications are in one
> jar that we copy as hexamples.jar.
> To run these against Hadoop 2 I can think of three simple solutions:
> (1) Stick with one jar and run "sleep" application in the TestMapReduce_1
> test as well.
> (2) Eliminate the test TestMapReduce_1 as TestHeartbeat_2 runs a MR job as
> well.
> (3) Require two different jars for Hadoop 2 and call them hclient.jar
> (containing "sleep" application) and hexamples.jar (containing "wordcount"
> application). For Hadoop 1, we would make two copies of the same
> hadoop-examples.jar application and call them hsleep.jar and examples.jar.
> The three approaches mentioned here would require least of changes. My
> inclination is towards (2).
> Let me know what you think and I can provide the patch.
