-------------------------------------
Summary: Support pluggable mechanism to specify proxy user settings
Key: HADOOP-10448
URL: https://issues.apache.org/jira/browse/HADOOP-10448
Project: Hadoop Common
Issue Type: Improvement
Components: security
Affects Versions: 2.3.0
Reporter: Benoy Antony
Assignee: Benoy Antony
We have a requirement to support large number of superusers. (users who
impersonate as another user)
(http://hadoop.apache.org/docs/r1.2.1/Secure_Impersonation.html)
Currently each superuser needs to be defined in the core-site.xml via
proxyuser settings. This will be cumbersome when there are 1000 entries.
It seems useful to have a pluggable mechanism to specify proxy user settings
with the current approach as the default.
