Robert Joseph Evans updated MAPREDUCE-4129:
-------------------------------------------
Resolution: Fixed
Fix Version/s: (was: 0.23.2)
3.0.0
2.0.0
0.23.3
Status: Resolved (was: Patch Available)
Thanks Ahmed, +1 the patch looks good. I don't think we really need any new tests because we are just changing log messages. I put this into trunk, branch-2, and branch-0.23.

------------------------------------
Attachment: MAPREDUCE-4129_rev2.patch
Thanks Tom for reviewing this! You are right. Also checking they are different doesn't seem to be sufficient, because the name could have been cut because of the length limits. I have updated the patch to check if the name was found in the legacyMap before printing the log message. Please let me know if you have further comments.

--------------------------------------
In your patch, the warning is printed every time a new group is created, even if the old and new names are the same. Don't you need to check that they are different?

Ahmed Radwan updated MAPREDUCE-4129:
------------------------------------
Attachment: MAPREDUCE-4129.patch
Attaching a patch addressing this issue. The patch modifies the behavior to only write the log message the first time the oldGroupName is found, instead of every time getGroup(..) is called.
I don't think we need a test case for this change as it is a straightforward change in message logging.
