grant command syntax in 0.95
Ted Yu 2013-08-22, 16:34
Hi,
In 0.94, grant.rb has the following:

Grant users specific rights.
Syntax : grant <user> <permissions> [<table> [<column family> [<column
qualifier>]]

In 0.95.2, I see:

Grant users specific rights.
Syntax : grant <user> <permissions> <table> <column family> <column
qualifier>

In 0.95.2, when I tried to grant permission on a table to user hrt_1, I got
some exception shown at the bottom of this email.

I want to confirm that in 0.95, granting permission for table must specify
column family and qualifier.

Thanks

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'
