Description

list_labels shouldn't raise ArgumentError if no labels are defined. The empty list is a valid return case, and anyway ArgumentError should be used when arguments to the command are erroneous. Here the command is well formed:

hbase(main):001:0> list_labels

ERROR: No auth label defined

Here is some help for this command:
List the visibility labels defined in the system.
Optional regular expression parameter could be used to filter the labels being returned.
Syntax : list_labels

For example:

    hbase> list_labels 'secret.*'
    hbase> list_labels
