-------------------------------------
Summary: Scan "show few" long option contains a space
Key: ACCUMULO-2747
URL: https://issues.apache.org/jira/browse/ACCUMULO-2747
Project: Accumulo
Issue Type: Bug
Components: shell
Affects Versions: 1.4.5

Reporter: Sean Busbey
Priority: Minor
the "show few" option on the scan command has a space instead of a dash. It's
confusing and inconsistent.

Expected: dash in name, or other means to not include escaping
Workaround: use short form (-f) or escape the space as shown above.
