Eric Yang created HADOOP-15996: ---------------------------------- Summary: Plugin interface to support more complex usernames in Hadoop Key: HADOOP-15996 URL: https://issues.apache.org/jira/browse/HADOOP-15996 Project: Hadoop Common Issue Type: New Feature Components: security Reporter: Eric Yang
Hadoop does not allow support of @ character in username in recent security mailing list vote to revert HADOOP-12751. Hadoop auth_to_local rule must match to authorize user to login to Hadoop cluster. This design does not work well in multi-realm environment where identical username between two realms do not map to the same user. There is also possibility that lossy regex can incorrect map users. In the interest of supporting multi-realms, it maybe preferred to pass principal name without rewrite to uniquely distinguish users. This jira is to revisit if Hadoop can support full principal names without rewrite and provide a plugin to override Hadoop's default implementation of auth_to_local for multi-realm use case. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
