Subject [jira] [Updated] (MAPREDUCE-3369) Migrate MR1 tests to run on MR2 using the new interfaces introduced in MAPREDUCE-3169
Date Thu, 24 Nov 2011 04:07:40 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3369?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ahmed Radwan updated MAPREDUCE-3369:

    Attachment: mv-cp_rev2.sh

This the updated patch after rebase on trunk to pick HADOOP-7590 mavenization changes. The
patch is divided - as before - into part1 and part2, with part1 equivalent to the series on
commands in mv-cp_rev2.sh, and part2 is the diffs after moving the files.

I have excluded 4 classes out of the 29 test classes from the new patch because they depend
on example classes from the newly introduced "examples" mvn module in HADOOP-7590. Adding
this dependency would have introduced a cycle. I have discussed this issue with tucu offline,
and having tests in mvn modules dependent on the examples mvn module will be problematic because
these example classes typically depend on classes on the rest of the modules. 

One option could be moving these tests to the examples module, but we also thought it is not
a clean solution. So I am excluding these classes from this patch so it can be applied cleanly.

We need to address later the issue with tests using examples in the new mvn organization.
