Doing that will balance the block writing but I think here you loose the concept of physical rack awareness. Let's say you have 2 physical racks, one with 2 servers and one with 4. If you artificially tell hadoop that one rack has 3 servers and the other 3 you are loosing the concept of rack awareness. You're not guaranteeing that each physical rack contains at least a replica of each block.
So if you have 2 racks with different number of servers, it's not possible to do proper rack awareness without filling the disks of the rack with less servers first. Am I right or am I missing something? -- View this message in context: http://lucene.472066.n3.nabble.com/rack-awareness-unexpected-behaviour-tp4086029p4093337.html Sent from the Hadoop lucene-users mailing list archive at Nabble.com.
