For access security, which controls what users and applications can do with data, we offer Apache Sentry – the standard, open source, unified authorization engine for enforcing role- based access controls (RBAC) across the Hadoop ecosystem. It provides unified access control for data as well as metadata stored in Hadoop. Enterprises can define the privileges for data sets that that will be enforced from multiple access paths including HDFS, Apache Hive, Impala, Cloudera Search as well as Apache Pig, Apache MapReduce/Yarn via HCatalog.
