Introducing Cloudera Navigator
Cloudera Navigator is a fully integrated data management tool for the Hadoop platform. Data management capabilities are critical for enterprise customers that are in highly regulated industries and have stringent compliance requirements.
- Auditing data access and verifying access privileges - Cloudera Navigator allows administrators to configure, collect, and view audit events, to understand who accessed what data and how. Cloudera Navigator also allows administrators to generate reports that list the HDFS access permissions granted to groups.Cloudera Navigator tracks access permissions and actual accesses to all data objects in HDFS, Hive, HBase, and Cloudera Impala to help answer questions such as - who has access to which data object(s), which data objects were accessed by a user, when was a data object accessed and by whom, what data assets were accessed using a service, which device was used to access, and so on. Cloudera Navigator auditing supports tracking access to:
- HDFS data accessed through HDFS, Hive, HBase, Cloudera Impala services
- HBase and Impala operations
- Hive metadata
- Searching metadata and visualizing lineage - Cloudera Navigator metadata management features allow DBAs, data modelers, business analysts, and data scientists to search for, amend the properties of, and tag data objects.
In addition, to satisfy risk and compliance audits and data retention policies it is important to be able to answer questions such as: where did the data come from, where is it used, what are the consequences of purging or modifying a set of data objects. Cloudera Navigator supports tracking the lineage of files, directories, tables, columns, MapReduce and YARN jobs, Hive queries, Pig scripts, and Oozie workflows.
