0.16.1 breaks backwards API compatibility with fix for HADOOP-2808
------------------------------------------------------------------
Key: HADOOP-3059
URL: https://issues.apache.org/jira/browse/HADOOP-3059
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.16.1
Reporter: Subramaniam Krishnan
Fix For: 0.16.2
HADOOP-2808 introduced a new signature for the copy method that takes an
overwrite flag.
Before this patch the behavior, for the pre-existing copy method, was that if
the destination existed an IOException was thrown. After this patch the
behavior, for the pre-existing copy method, is that if the destination exists
it is overwritten.
The behavior of the pre-existing copy method should not have changed.
