Hudson commented on HADOOP-5500:
--------------------------------

Integrated in Hadoop-trunk #827 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-trunk/827/])
    . Where field names are absent permit the number of fields to be
sufficient to construct the select query. Contributed by Enis Soztutar

> DBOutputFormat expects the column names to be included in the query. However, if the
field names are not available, only the number of fields is sufficient for preparing the SELECT
query. 
> This issue will add API support for supplying the number of fields in DBOutputFormat#setOutput().

> Please see HADOOP-4955 and HADOOP-5307 for related context.
