Rajkumar Singh created HIVE-19469:
-------------------------------------

             Summary: HiveServer2: SqlStdAuth take too much time while doing checkFileAccessWithImpersonation if the table location has too many files/dirs
                 Key: HIVE-19469
                 URL: https://issues.apache.org/jira/browse/HIVE-19469
             Project: Hive
          Issue Type: Task
          Components: HiveServer2
    Affects Versions: 2.1.0
            Reporter: Rajkumar Singh


HiveServer2 doAuthorization call takes too much time while doing checkFileAccessWithImpersonation if the table location has too many files/dirs which increases the query compilation time.

the improvement we can make here is to parallelize checkFileAccessWithImpersonation call.
