Hey Tobi,
Some folks from the Condor team at Wisconsin claimed to have this working
(see https://issues.apache.org/jira/browse/HDFS-573), but never posted a
patch. Perhaps you could contact them and see if they have the patch ready
for public consumption?
Regards,
Jeff

Hey 易剑,
Your proposed system sounds quite a bit like Zebra, which is a contributed
project under the Pig subproject: http://wiki.apache.org/pig/zebra. Have you
taken a look at Zebra?
Thanks,
Jeff

As discussed on the mailing list, as the number of disk drives per server
increases, it would be useful to allow the DataNode's policy for new block
placement to grow in sophistication from the current round-robin strategy.

As discussed on the mailing list, it would be useful if the DfsClient could
measure the distribution of blocks across devices for an individual DataNode.

Currently, the DataNode will not start up if a single volume has failed;
