Jakob Homan commented on HADOOP-7182:
-------------------------------------
our policy has been to leave deprecated classes in for two releases and then
remove them, to give the community time to move over to the new classes. I
usually mark it as @Deprecated // in XX to be removed in XX+2 so people can
easily tell when they can safely delete the class.
> remove stub implementation of HardLink from FileUtil, after fixing any
> remaining dependencies

> Project: Hadoop Common

>
> This is the third part of a refactoring of HardLink:
> 1. HADOOP-7133 moved HardLink from an inner class of FileUtil to a
> stand-alone class, but left a stub class in FileUtil to prevent breaking
> clients in HDFS.
> 2. HDFS-1445 changes the clients in HDFS to point at the new implementation.
> 3. After HDFS-1445 is committed, this ticket is to clean up the code by
> removing the backward-compatibility stub.
