dfs web interfaces should run as a configurable user account
------------------------------------------------------------
Key: HADOOP-2614
URL: https://issues.apache.org/jira/browse/HADOOP-2614
Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE
Currently, web interfaces (i.e. browseDirectory.jsp, browseBlock.jsp, etc.) run
in each Datanode. The web interfaces use the corresponding Datanode account
(the user who ever started the Datanode) to connect to Namenode. Usually,
Datanodes are started by administrators. As a consequence, the web interfaces
have administrator access, which is undesirable. The web interfaces account
should be configurable.
