Hi,  
When I tried to get node statistics from ES cluster with 2 nodes on 2  
different machines, I got empty node statistics response

\*{  
cluster\_name: "rossCluster"  
nodes: { }  
}  
\*  
This happens after I start the second node. A short time after starting the  
second node, I can not get node statistics anymore. I am trying this on a  
CENTOS OS with version x86\_64 x86\_64 x86\_64 GNU/Linux.

Same things happen with single ES node. I removed sigar files from lib  
directory (JMX mode) and restarted again, but the result did not change.
