distcp overwrites destination files by default
----------------------------------------------
Key: HADOOP-1539
URL: https://issues.apache.org/jira/browse/HADOOP-1539
Project: Hadoop
Issue Type: Improvement
Components: util
Reporter: Senthil Subramanian
Fix For: 0.14.0
This is risky. distcp should instead accept a flag that indicates if
destination files can be overwritten (overwrite all files, overwrite only if
dest timestamp is older than source etc). The default behavior should be to not
overwrite any files.
