Given your other thread post, I'd say you may have an inconsistency in
the JDK deployed on the cluster. We generally recommend using the
Oracle JDK6 (for 1.0.4). More details on which version to pick can be
found at http://wiki.apache.org/hadoop/HadoopJavaVersions. In any
case, the JDK installation across the cluster has to be consistent
(you can check via a package tool such as yum, or via "java -version"
commands on each node).
