RegexAllExtractor doesn't ignore empty groups
---------------------------------------------

                 Key: FLUME-722
                 URL: https://issues.apache.org/jira/browse/FLUME-722
             Project: Flume
          Issue Type: Bug
          Components: Sinks+Sources
    Affects Versions: v0.9.4
            Reporter: Nicholas Verbeck
            Assignee: Nicholas Verbeck

Hi flume devs.

I saw a bug when using RegexAllExtractor: line 94:

         if(names.get(grp-1) != ""){
           Attributes.setString(e, names.get(grp-1), val);
         }

Please help to file a jira and correct it to use String.equal(), otherwise it 
doesn't ignore empty groups.

(I don't think I can open a issue at cloudera jira.)

Thanks,
Mingjie
