Followup to the original HADOOP-18582. Temporary path cleanup is re-enabled for -append jobs as these will create temporary files when creating or overwriting files. Contributed by Ayush Saxena
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.
