> From user@hbase, Allan Yan writes:
> There might be a bug for REST web service to get rows with given startRow and endRow.
> For example, to get a list of rows with startRow=testrow1, endRow=testrow2, I send GET
request:
> curl http://localhost:8123/TestRowResource/testrow1,testrow2/a:1
> And got StringIndexOutOfBoundsException.
> This was because in the RowSpec.java, parseRowKeys method, startRow value was changed:
> {code}
>        startRow = sb.toString();
>        int idx = startRow.indexOf(',');
>        if (idx != -1) {
>          startRow = URLDecoder.decode(startRow.substring(0, idx),
>            HConstants.UTF8_ENCODING);
>          endRow = URLDecoder.decode(startRow.substring(idx + 1),
>            HConstants.UTF8_ENCODING);
>        } else {
>          startRow = URLDecoder.decode(startRow, HConstants.UTF8_ENCODING);
>        }
> {code}
>  After change to this, it works:
> {code}
>        String row = sb.toString();
>        int idx = row.indexOf(',');
>        if (idx != -1) {
>          startRow = URLDecoder.decode(row.substring(0, idx),
>            HConstants.UTF8_ENCODING);
>          endRow = URLDecoder.decode(row.substring(idx + 1),
>            HConstants.UTF8_ENCODING);
>        } else {
>          startRow = URLDecoder.decode(row, HConstants.UTF8_ENCODING);
>        }
> {code}
