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
versions: namenode BV = ; datanode BV = 810220

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 ?

Hi Nachiket,
Thank you for your reply. But I don't think the page you recommend can solve
my problem.
The problem on your page is try to solve the namespace version
incompatibility. But what I meet it build version incompatibility.
