Examples of org.apache.hadoop.tools.DistCp.run()

org.apache.hadoop.tools.DistCp.run()
Implementation of Tool::run(). Orchestrates the copy of source file(s) to target location, by: 1. Creating a list of files to be copied to target. 2. Launching a Map-only job to copy the files. (Delegates to execute().) @param argv List of arguments passed to DistCp, from the ToolRunner. @return On success, it returns 0. Else, -1.
