Subject [jira] [Updated] (HDFS-6826) Plugin interface to enable delegation of HDFS authorization assertions
Date Fri, 22 Aug 2014 05:13:11 GMT

     [ https://issues.apache.org/jira/browse/HDFS-6826?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alejandro Abdelnur updated HDFS-6826:
-------------------------------------

    Attachment: HDFS-6826v7.1.patch

uploaded patch taking care of the testcases failures (needed a bit of defensive coding as
testcases are not always initializing everything), fixed javadoc warning.

audit warnings are unrelated (the come from the fs-encryption merge and they are being addressed
already).

> When Hbase data, HiveMetaStore data or Search data is accessed via services (Hbase region
servers, HiveServer2, Impala, Solr) the services can enforce permissions on corresponding
entities (databases, tables, views, columns, search collections, documents). It is desirable,
when the data is accessed directly by users accessing the underlying data files (i.e. from
a MapReduce job), that the permission of the data files map to the permissions of the corresponding
data entity (i.e. table, column family or search collection).
> To enable this we need to have the necessary hooks in place in the NameNode to delegate
authorization to an external system that can map HDFS files/directories to data entities and
resolve their permissions based on the data entities permissions.
> I’ll be posting a design proposal in the next few days.
