> It seems that getTableDescriptors() in master checks for A and C permissions while getTableNames() checks for any privilege on the table. The reasoning is explained here: https://issues.apache.org/jira/browse/HBASE-12564?focusedCommentId=14234504&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14234504
> We should change the shell command for {{list}} to use the getTableNames() version because of this. Otherwise a user having only R or W cannot list the table name.
> This has been reported from a user here: https://community.hortonworks.com/questions/10742/why-does-a-user-need-create-permission-for-list-co.html#comment-11000.
> While we are at it, should we revisit the fact that you cannot get a table descriptor if you have only R or W? It seems strange that you cannot even know the CF names of a table that you can read from. I could not find info about the "describe" privileges on SQL databases. However, if there are use cases where Table descriptor might contain sensitive info, the current semantics seems fine. cc [~apurtell] and [~mbertozzi].
