Subject: hdfs dfsclient, possible to force storage datanode ?

hi list,

we have 52 DNs and more hundred clients they are store and read data from hdfs. one rack has
3 DNs and about 15 clients.

it is possible to force (if space is available) that  these 15 clients prefer the 3 DNs located
in there own rack to store and read data?

racklocation.conf with "org.apache.hadoop.net.NetworkTopology" is allready in use, but this
does not help in this case

thanks
