(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. -- This message was sent by Atlassian JIRA (v6.2#6252)
