remove stub implementation of HardLink from FileUtil, after fixing any
remaining dependencies
---------------------------------------------------------------------------------------------
Key: HADOOP-7182
URL: https://issues.apache.org/jira/browse/HADOOP-7182
Project: Hadoop Common
Issue Type: Improvement
Components: util
Affects Versions: 0.23.0
Reporter: Matt Foley
Assignee: Matt Foley
Priority: Minor
Fix For: 0.23.0
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.
