[jira] [Updated] (HBASE-11434) [AccessController] Disallow inbound
cells with reserved tags
[ https://issues.apache.org/jira/browse/HBASE-11434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell updated HBASE-11434:
-----------------------------------
Description:
The AccessController allows users to store cells with ACL tags encoded by the client. This isn't a security issue currently, because in order to store the cell the user must have a relevant WRITE grant, and the user is allowed to specify whatever ACL for the cell they'd like. However it could become a correctness problem in the future, if we introduce format sanity checking or the like, so let's disallow inbound mutations containing cells with reserved tags like the VisibilityController does.
The check is skipped if the active user is a superuser. First, superusers are allowed to do anything. Second, replication (as superuser) must be able to store incoming cells with ACL tags.
