ACCESS POLICIES BASED ON HDFS EXTENDED ATTRIBUTES

摘要

Systems, computer program products and methods implementing access control on a distributed file system are described. A policy engine enforces one or more policies to access a data item stored in the distributed file system by utilizing non-system extended attributes of the data item. The policy engine receives, from a client device, a request to access the data item. The policy engine determines a policy for access the data item. The policy specifies one or more conditions for accessing the data item in one or more extended attributes. The one or more extended attributes are associated with the data item in the distributed file system. The policy determines whether to grant the request to access the data item according to values of the one or more extended attributes.
