It was just not closed. > Adding user and service-to-service authentication to Hadoop > ----------------------------------------------------------- > > Key: HADOOP-4343 > URL: https://issues.apache.org/jira/browse/HADOOP-4343 > Project: Hadoop Common > Issue Type: New Feature > Reporter: Kan Zhang > Assignee: Kan Zhang > Priority: Blocker > Fix For: 0.23.0, 0.20.203.0 > > > Currently, Hadoop services do not authenticate users or other services. As a > result, Hadoop is subject to the following security risks. > 1. A user can access an HDFS or M/R cluster as any other user. This makes it > impossible to enforce access control in an uncooperative environment. For > example, file permission checking on HDFS can be easily circumvented. > 2. An attacker can masquerade as Hadoop services. For example, user code > running on a M/R cluster can register itself as a new TaskTracker. > This JIRA is intended to be a tracking JIRA, where we discuss requirements, > agree on a general approach and identify subtasks. Detailed design and > implementation are the subject of those subtasks. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
