Hi Keshav, What you want is not possible I guess. You can't submit anything into HDFS without the namenode. Datanodes reports their local blocks into the namenode. If the namenode does not know them it will instruct the datanode to delete them.
But whats the point? If you submit local files to HDFS (via the namenode ) from a datanode, the nn will assign to first block placement directly on that dn (provided there is room etc.) and start replicating from there.
