J-D:
Thanks for your kind offer.
Full output from a reducer contains CIQ proprietary code information which I
cannot disclose.

Also the size of data node logs would be big.

It would be nice if people from Cloudera can take a look. Or they can
outline their hadoop release schedule which covers hdfs-724 and hdfs-895.
