---------------------------------------
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)}}
