Updating the hadoop version of branch-3.3 to 3.3.9-SNAPSHOT pending agreement on what number its future release should take. Using 3.3.9-SNAPSHOT puts space in for other incremental releases, while avoiding creating JIRA release ordering and autocompletion confusion the way adding a 3.3.10 or higher version would do.

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.
