Cheolsoo Park commented on SQOOP-501:
-------------------------------------
While working on SQOOP-494, I realized that it should be not too hard to
implement this. In Java, if we call read() or readLine() on a BufferedReader or
similar, characters that we type do not show up unless we explicitly print them
back to stdout. In fact, ssh behaves in the same way, so it does not print any
characters when we type password.
Only thing that we have to handle seems like backspace (as Bilung pointed out
at last meeting). We should interpret backpsace and delete a previous char
rather than save it as input. Other than that, I believe that it should be
straightforward to implement this.
We might go fancy by printing a mask character instead of printing nothing, but
only if time permits, I guess... :-)
