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

Akira AJISAKA updated MAPREDUCE-5830:
-------------------------------------

    Attachment: MAPREDUCE-5830.patch

Attaching a patch to add {{getTaskLogUrl(String, String, String)}}. The method always throws {{RuntimeException}}, however, I think it's not a bad option because this method is not called at runtime.

> 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.
