Subject hdfs dfsclient, possible to force storage datanode ?
Date Wed, 20 Aug 2014 14:14:16 GMT
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
