Currently the passwords of all the users of zeppelin are stored in shiro.ini file in plain text format. I want to encrypt these passwords and store in mysql database. I am struck with this since many days as I am new to the technology. I don't have LDAP or AD. Also no kerberization is implemented. Ambari UI is being used. Looking to achieve it through configuration changes itself rather than changing the existing functionality completely. Can anyone please guide me to achieve the same.
