Subject Re: how to find out name node is running
Date Tue, 25 Mar 2008 20:50:37 GMT
That's relying on Java Virtual Machine process status tool, similar to 'ps
aux|grep java' on a Linux?

I think the question is whether there is any API from Hadoop library which
can monitor the namenode
through a Java API without relying 3rd party utility tool.  Am I right?
