[jira] Created: (HADOOP-3059) 0.16.1 breaks backwards API
compatibility with fix for HADOOP-2808
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.

[jira] Resolved: (HADOOP-3059) 0.16.1 breaks backwards API
compatibility with fix for HADOOP-2808

Chris Douglas resolved HADOOP-3059.
-----------------------------------
Resolution: Won't Fix
HADOOP-2808 didn't introduce a new signature for copy; it enforced the existing one. As indicated in the JIRA, setting the "overwrite" parameter had no effect on the copy. This isn't an API change; the overwrite formal was added to a private, static function. The former behavior can be restored by setting overwrite to false.
