Vihang Karajgaonkar commented on HIVE-13589:
--------------------------------------------
I think we should not put a limitation that -p should be the last argument.
This would be a bad user-experience. If the main reason for this issue is to
avoid showing the password in the command history, the ideal behavior should be
that user does not provide a password while connecting and beeline should
prompt for one when it finds that there is no password provided.
The issue is due to the code block below. When the password is null, it sets it
to empty string due to which beeline does not prompt for the password when it
is not provided. I think we should fix this behavior which would provide a way
for the user to achieve the same without limiting the usability of the -p
argument.

private String constructCmd(String url, String user, String pass, String
driver, boolean stripPasswd) {
String com = "!connect "
+ url + " "
+ (user == null || user.length() == 0 ? "''" : user) + " ";
if (stripPasswd) {
com += PASSWD_MASK + " ";
} else {
com += (pass == null || pass.length() == 0 ? "''" : pass) + " ";
}
com += (driver == null ? "" : driver);
return com;
}

> Specifying connection string using commandline options in beeline is
> convenient, as it gets saved in shell command history, and it is easy to
> retrieve it from there.
> However, specifying the password in command prompt is not secure as it gets
> displayed on screen and saved in the history.
> It should be possible to specify '-p' without an argument to make beeline
> prompt for password.
