Subject [jira] [Commented] (HBASE-10834) Better error messaging on issuing grant commands in non-authz mode
Date Thu, 14 Aug 2014 01:12:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14096380#comment-14096380

Srikanth Srungarapu commented on HBASE-10834:

Tested the patch on the secure cluster. The output:
hbase(main):003:0> grant "test", "RWCXA"
0 row(s) in 0.3920 seconds

The output on non-secure cluster is as follows:
hbase(main):002:0> grant "test", "RWXCA"

ERROR: Command not supported as authorization is turned off

>          Issue Type: Bug
>          Components: shell
>    Affects Versions: 0.94.17

>            Assignee: Srikanth Srungarapu
>            Priority: Trivial

> Running the below sequence of steps should give a better error messaging rather than
"table not found" error. 
> {code}
> hbase(main):009:0> grant "test", "RWCXA"
> ERROR: Unknown table _acl_!
> Here is some help for this command:
> Grant users specific rights.
> Syntax : grant <user> <permissions> [<table> [<column family>
[<column qualifier>]]
> permissions is either zero or more letters from the set "RWXCA".
> READ('R'), WRITE('W'), EXEC('X'), CREATE('C'), ADMIN('A')
> For example:
>     hbase> grant 'bobsmith', 'RWXCA'
>     hbase> grant 'bobsmith', 'RW', 't1', 'f1', 'col1'
> {code}
> Instead of ERROR: Unknown table _acl_!, hbase should give out a warning like "Command
not supported in non-authz mode(as acl table is only created if authz is turned on)"
