[jira] [Created] (HIVE-6851) HS2 proxy user - should refresh proxy
user list only once
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.
