-------------------------------------

             Summary: ledger ids are long, but they are stored in zk as 10 
characters max, which fundamentally limits them at 9 billion
                 Key: BOOKKEEPER-421
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-421
             Project: Bookkeeper
          Issue Type: Bug
            Reporter: Ivan Kelly
            Priority: Critical
             Fix For: 4.2.0


{code}
    public static String getZKStringId(long id) {
        return String.format("%010d", id);
    }
{code}

Simple to fix, but we need it be backward compatible, which also shouldn't be a 
problem.
