> 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
