Post users: need admin-only access to HDFS
-------------------------------------------
Key: HADOOP-2230
URL: https://issues.apache.org/jira/browse/HADOOP-2230
Project: Hadoop
Issue Type: New Feature
Environment: All
Reporter: Allen Wittenauer
When user support gets added to HDFS, administrators are going to need to be
able to set the namenode such that it only allows connections/interactions from
the administrative user. This is particularly important after upgrades and for
other administrative work that may require the changing of user/group
ownership, permissions, location of files within the HDFS, etc.
