Subject Re: Setting up a multi-node cluster
Date Thu, 29 Aug 2013 06:47:45 GMT
My first node is running and second node is not running in this case

I tried telnet from second node to first node. Following is the stdout

# telnet 10.96.10.207 7000
Trying 10.96.10.207...
Connected to 10.96.10.207.
Escape character is '^]'.
quit
Connection closed by foreign host.

I see the same output for 7199 & 9160 ports. is this correct. I am not
seeing the telnet session as something like telnet>
----------
But when I tried with 7001. I am seeing the below output

# telnet 10.96.10.207 7001
Trying 10.96.10.207...
telnet: connect to address 10.96.10.207: Connection refused

I see the same output for 61620 & 61621 ports
----------

Please suggest
