-----------------------------------
Assignee: (was: Sergio Peña)
> Hive/Sentry plugin doesn't check URI effectiveness when calling GRANT
> ---------------------------------------------------------------------
>
> Key: SENTRY-1694
> URL: https://issues.apache.org/jira/browse/SENTRY-1694
> Project: Sentry
> Issue Type: Bug
> Components: Hive Plugin
> Affects Versions: 1.7.0
> Reporter: Sergio Peña
> Priority: Minor
>
> Sentry doesn't check URI effectiveness when executing GRANT commands on Hive,
> even though it requires full URI path in HDFS.
> GRANT is allowing users to provide any invalid URI paths, like below:
> {noformat}
> GRANT ALL ON URI "hdfs://hdfs://localhost:8020:8020///tmp/myjar.jar" TO ROLE
> role1"
> {noformat}
> If the user attempts to create a function from the correct URI, then Sentry
> won't find the URI and it will fail with a permission denied.
> {noformat}
> Error: Error while compiling statement: FAILED: SemanticException No valid
> privileges
> User sergio does not have privileges for CREATEFUNCTION
> The required privileges:
> Server=server1->URI=hdfs://localhost:8020/tmp/myjar.jar->action=*;
> (state=42000,code=40000)
> {noformat}
> I noticed that the Hive/Sentry plugin checks if the URI is normalized during
> the CREATE FUNCTION command. If not, it will skip it and continue with other
> available URI.
> I think we should apply the same normalization check during the GRANT to at
> least alert the user that URI might be wrong.
