I know it is a little late, but I had this same problem and here is what finally worked for me.
I downloaded Cygwin to my machine and used it with a “scp” command
Example:
me@mycomputer /cygdrive/c/
$ scp -P 2222 ./test.txt root@127.0.0.1:~
it will ask you about the RSA token – press y and hit enter and then
it will ask you for the root password (hadoop)
