-------------------------------------
Attachment: HDFSPluggableAuthorizationProposal.pdf
Uploading a proposal that includes usecases, current state of things, a
proposal and how the proposal would enable a HiveMetaStore&Sentry driven
authorizations for files belonging to tables.
> Plugin interface to enable delegation of HDFS authorization assertions

> Key: HDFS-6826
> URL: https://issues.apache.org/jira/browse/HDFS-6826
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: security
> Affects Versions: 2.4.1
> Reporter: Alejandro Abdelnur
> Assignee: Alejandro Abdelnur
> Attachments: HDFSPluggableAuthorizationProposal.pdf

>
> 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.
