[jira] [Updated] (HADOOP-9436) NetgroupCache does not refresh membership correctly
[ https://issues.apache.org/jira/browse/HADOOP-9436?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Allen Wittenauer updated HADOOP-9436: - Status: Open (was: Patch Available) NetgroupCache does not refresh membership correctly --- Key: HADOOP-9436 URL: https://issues.apache.org/jira/browse/HADOOP-9436 Project: Hadoop Common Issue Type: Bug Affects Versions: 0.23.7, 2.0.3-alpha, 3.0.0 Reporter: Kihwal Lee Assignee: Kihwal Lee Attachments: HADOOP-9436.patch NetgroupCache is used to get around the problem of inability to obtain a single user-to-groups mapping from netgroup. For example, the ACL code pre-populates this cache, so that any user-group mapping can be resolved for all groups defined in the service. However, the current refresh code only adds users to existing groups, so a loss of group membership won't take effect. This is because the internal user-groups mapping cache is never invalidated. If this is simply invalidated on clear(), the cache entries will build up correctly, but user-group resolution may fail during refresh, resulting in incorrectly denying accesses. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
