Hi all,
I downloaded Hadoop-1.1.1 tar ball from one of the mirrors and
configured it in psuedo-distributed mode.

Namenode starts fine but datanode fails to start because of version mismatch.

The value of hadoop.relaxed.worker.version.check property (related to
https://issues.apache.org/jira/browse/HADOOP-8209) doesn't help in
this case since the major+minor versions don't match. Sounds like a
bug to me, we seem to have missed changing the datanode version before
the release. Can someone please confirm?

Here is the error:
2012-12-12 22:17:42,251 ERROR

Hi,

Did you run a build on the tarball before using it, by any chance?

Thanks folks.

Zizon: The JIRA you suggested (HADOOP-8968) has a fix version of
1.2.0. It can't be used on the 1.1.1 release.

Harsh: I did try rebuilding the examples jar by doing "ant examples"
which failed (for a different reason), it seems like that changed the
version of the datanode for some reason that caused this issue.

The line that caused the problem in build.xml is
<property name="version" value="1.1.2-SNAPSHOT"/>

Is that the right thing to do? Or, should we ship build.xml with
version value as 1.1.1 in released tarballs?

I do think running a build would cause that. Doing an 'ant clean'
would resolve it for you.

But I agree that the default version may perhaps be the release itself
(although then it gets harder to identify that the user ran a build?),
please file a JIRA for further discussion.

the version is not match,as the log indicated:
namenode:1.1.1
datanode:1.1.2-SNAPSHOT

hadoop.relaxed.worker.version.check only works when version match(relax
just revision check).

you may have a try of hadoop.skip.worker.version.check.
see https://issues.apache.org/jira/browse/HADOOP-8968
