Description

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.
