Using a KeyStore file instead of db_root_password

[Sungwoo Park]

Hello,

I have a question on installing Ranger. Currently we specify the password
for Ranger database (which is MySQL) with db_root_password in
ranger-admin-install.properties, e.g.:

db_root_user=root
db_root_password=passwd

I wonder if there is an alternative way of specifying the password with a
KeyStore file (jceks). Or, it the file ranger-admin-install.properties just
supposed to be removed after installing Ranger?

Thanks,
