[jira] Updated: (HBASE-1184) HColumnDescriptor is a little too restrictive with family names

["Toby White (JIRA)" <ji...@apache.org>]

Toby White updated HBASE-1184:
------------------------------

    Status: Patch Available  (was: Open)

The attached patch fixes the issue.

It reverses the sense of the test, and simply tests that each character is not a control character.

It also tidies up the error message slightly (removing the reference to ending with colons, since that is tested in a separate check)

> HColumnDescriptor crrently requires of its family names that they be letters, digits, underscores or periods.
> Character.isLetterOrDigit(b[i]) || b[i] == '_' || b[i] == '.'
> It would be nice if it let rather more characters be used (personally, I'd like to use a hyphen!)
