Exception happen when start a single node
Hi all,

One of my machine fall into the black list, then I want to restart it. But
exception happens as following:

2010-01-29 10:32:23,247 FATAL
org.apache.hadoop.hdfs.server.datanode.DataNode: Incompatible build

Anyone know this issue? I know that hadoop have a requirement that each
node's hadoop version should been the same, but does it also require the
same build version? And what determine the build version ?
