Subject [jira] [Created] (HIVE-6851) HS2 proxy user - should refresh proxy user list only once
Date Sun, 06 Apr 2014 00:48:14 GMT
Thejas M Nair created HIVE-6851:
-----------------------------------

             Summary: HS2 proxy user - should refresh proxy user list only once
                 Key: HIVE-6851
                 URL: https://issues.apache.org/jira/browse/HIVE-6851
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2, Security
    Affects Versions: 0.13.0
            Reporter: Thejas M Nair


With the change in HIVE-6800, HadoopShimsSecure. authorizeProxyAccess function calls ProxyUsers.refreshSuperUserGroupsConfiguration(conf)
every time.

ProxyUsers.refreshSuperUserGroupsConfiguration(conf) applies regex on all the params in hive
configuration object, but this configuration object can have several hundreds of params. It
is better to do this only once in hiveserver2.

Note that this code is used only when proxy user feature is used in hiveserver2.
