Subject [jira] [Commented] (HBASE-10619) Don't allow non super users to disable/drop system tables
Date Tue, 07 Apr 2015 16:41:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14483463#comment-14483463

Andrew Purtell commented on HBASE-10619:
----------------------------------------

bq. Please note that for disable table, there is an extra check for META table. Even for super
user this op is not allowed. 

This is fine as a special case IMO, if the META table is disabled then everything immediately
falls over. I think we need the same protection on the namespace table too. The superuser
should be able to otherwise create, modify, enable/disable, and delete tables in the system
namespace.

> We should treat NS table just like META table, which is having checks so that user can
not disable/drop.
