NullPointerException in StatusHttpServer
----------------------------------------
Key: HADOOP-309
URL: http://issues.apache.org/jira/browse/HADOOP-309
Project: Hadoop
Type: Bug
Components: dfs, mapred
Versions: 0.3.2
Reporter: Konstantin Shvachko
The NullPointerException happens in the constructor of StatusHttpServer because
the System property "hadoop.log.dir" is undefined.
I see it trying to start the Namenode directly without using any scripts.
Exception in thread "main" java.lang.NullPointerException

In general I think the sources should not rely on the system properties and
environment variables defined in hadoop scripts.
