[jira] [Commented] (MAPREDUCE-5830) HostUtil.getTaskLogUrl is not backwards binary compatible with 2.3

["Jason Lowe (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13966625#comment-13966625 ] 

Jason Lowe commented on MAPREDUCE-5830:
---------------------------------------

My apologies, HostUtil is in MapReduce not YARN, moving to appropriate project.  Hive 0.13 is using HostUtil.getTaskLogUrl and broke when moving from 2.3 to 2.4.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>    Affects Versions: 2.4.0

> 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.
