Subject how to select the position of a block
Date Wed, 07 Dec 2011 03:06:06 GMT
Hadoop:The Definitive Guide  said that when the client is out of the cluster, hadoop will select
the storage position of a block randomly,but it will not select the datanode which is too
busy or too full.

so i want to kown that  how hadoop judge or measure a datanode is full or not?
