Hudson commented on MAPREDUCE-5830:
-----------------------------------
SUCCESS: Integrated in Hadoop-trunk-Commit #5743 (See
[https://builds.apache.org/job/Hadoop-trunk-Commit/5743/])
MAPREDUCE-5830. Added back the private API HostUtil.getTaskLogUrl(..) for
binary compatibility with older clients like Hive 0.13. Contributed by Akira
Ajisaka. (vinodkv:

> Key: MAPREDUCE-5830
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5830
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: Jason Lowe
> Assignee: Akira AJISAKA
> Priority: Blocker
> Fix For: 2.4.1
>
> Attachments: MAPREDUCE-5830.patch
>
>
> HostUtil.getTaskLogUrl used to have a signature like this in Hadoop 2.3.0 and
> earlier:
> public static String getTaskLogUrl(String taskTrackerHostName, String
> httpPort, String taskAttemptID)
> but now has a signature like this:
> public static String getTaskLogUrl(String scheme, String taskTrackerHostName,
> String httpPort, String taskAttemptID)
> This breaks source and binary backwards-compatibility. MapReduce and Hive
> both have references to this, so their jars compiled against 2.3 or earlier
> do not work on 2.4.
