Subject HDFS block placement
Date Fri, 26 Jul 2013 11:44:53 GMT

I am a bit confused about the block placement in Hadoop. Assume that 
there is no replication and a task (map or reduce) writes a file to 
HDFS, will be all blocks stored on the same local node (the node on 
which the task runs)? I think yes but I am node sure.

Kind Regards,
Lukas Kairies
