|
|
The <codeph>REFRESH AUTHORIZATION</codeph> 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 <codeph>INVALIDATE
|
|
METADATA</codeph>.
|
|
</p>
|
|
|
|
<p>
|
|
Once issued, the <codeph>REFRESH AUTHORIZATION</codeph> statement cannot be cancelled.

See <xref href="impala_authorization.xml#authorization">Impala Authorization</xref> for
|
|
information on enabling and using authorization in Impala.
