Legacy Integrations
This section includes how-to guides for Immuta's legacy integrations.
Immuta offers both fine- and coarse-grained protection for Hive and Impala tables. However, additional protections are required to ensure that users cannot gain unauthorized access to data by connecting to Hive or Impala directly. Cloudera recommends using the Sentry service to secure access to Hive and Impala. As an alternative, this guide details steps that CDH cluster administrators can take to lock down Hive and Impala access without running the Sentry service.
Hadoop has the concept of a Group Mapping Service, which is a way to retrieve groups corresponding to a provided user/Kerberos principal. By default, Hadoop services (HDFS, Hive, Impala, etc.) retrieve a user's groups from the local OS by way of the ShellBasedUnixGroupsMapping class. This guide shows you how to enrich this data to include the user's current project in Immuta.
