History

Steve Loughran b6dc00f481 HADOOP-16775. DistCp reuses the same temp file within the task for different files. Contributed by Amir Shenavandeh. This avoids overwrite consistency issues with S3 and other stores -though given S3's copy operation is O(data), you are still best of using -direct when distcp-ing to it.

README

DistCp (distributed copy) is a tool used for large inter/intra-cluster copying. 
It uses Map/Reduce to effect its distribution, error handling and recovery, 
and reporting. It expands a list of files and directories into input to map tasks, 
each of which will copy a partition of the files specified in the source list.
