REFRESH AUTHORIZATION Statement
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
Once issued, the
REFRESH AUTHORIZATION statement cannot be cancelled.
See Impala Authorization for information on enabling and using authorization in Impala.
Usage notes: If authorization is not enabled, Impala returns an error.
