Description

FileSystem has the API

public void copyFromLocalFile(boolean delSrc, boolean overwrite, Path[] srcs, Path dst)

This API provides overwrite option. But the mapping command line doesn't have this option. To maintain the consistency and better usage the command line option also can support the overwrite option like to put the files forcefully. ( put [-f] <srcpath> <dstPath>) and also for copyFromLocal command line option.
