REFRESH AUTHORIZATION statement
The REFRESH AUTHORIZATION statement explicitly
refreshes authorization data, including privileges and principals. When
there is an external update to authorization metadata, use this statement to
force Impala to refresh its authorization data without having to wait for
the Ranger polling or run INVALIDATE METADATA.
Once issued, the REFRESH AUTHORIZATION statement cannot be cancelled.
Syntax:
REFRESH AUTHORIZATIONUsage notes: If authorization is not enabled, Impala returns an error.
Added in: Impala 3.2
