Subject [jira] [Created] (RANGER-2279) Reduce the time spent changing passwords during Ranger Admin start
Date Tue, 06 Nov 2018 12:58:00 GMT
Pradeep Agrawal created RANGER-2279:
---------------------------------------

             Summary: Reduce the time spent changing passwords during Ranger Admin start
                 Key: RANGER-2279
                 URL: https://issues.apache.org/jira/browse/RANGER-2279
             Project: Ranger
          Issue Type: Improvement
          Components: Ranger
    Affects Versions: 1.0.1, 1.1.1, 1.2.1
            Reporter: Pradeep Agrawal
            Assignee: Pradeep Agrawal
             Fix For: 1.0.1, 1.1.1, 1.2.1


{{ChangePasswordUtil}} takes 12-14 seconds to change a password. Its first invocation takes
25-30 seconds (additional time spent creating embedded service-defs). During the initial start
of Ranger Admin there are 4 passwords being changed (admin, rangerusersync, rangertagsync,
keyadmin), total time for password change is ~74 seconds.

Based on {{ChangePasswordUtil}}'s logs, most of the time is spent on setup, and the actual
password change is very quick.

So it will be better to change multiple passwords in one request (by sending multiple users
passwords config in single run of {{ChangePasswordUtil)}}
