---------------------------------
Summary: Add API to Sentry Service that allows clients to read the
service's config values
Key: SENTRY-415
URL: https://issues.apache.org/jira/browse/SENTRY-415
Project: Sentry
Issue Type: Task
Affects Versions: 1.4.0
Reporter: Lenni Kuff
It would be useful to add an API to Sentry Service that allows Sentry Service
clients to read the service's configuration values. The Hive Metastore has a
similar API:
"String getConfigValue(String propertyName, String defaultValue)"
One specific use case for Sentry is to make it possible for clients that cache
policy metadata (e.g. Impala) to read the admin group(s) so they can also cache
this information and authorize GRANT/REVOKE requests without making an RPC to
the Sentry service. The client could periodically refresh the configuration
information to ensure it is up to date.
