Hi,

I am new to Cassandra, and I want to create a 2 node cluster on the SAME machine running windows for testing my application before we get new hardware.
I am facing "No other nodes seen! Unable to bootstrap"
The first node starts successfully while the second node gives me the error.
All ports are open and the firewall is off.

I changed cassandra.bat for the 2node (transport=dt_socket address=8889 and jmxremote.port=8081)
Attached is the config file for the second node--->
Here are some configuration for the second node:
 <AutoBootstrap>true</AutoBootstrap>
...
<Seeds>
      <Seed>127.0.0.1</Seed>
  </Seeds>
...
<ListenAddress>127.0.0.2</ListenAddress>
  <!-- internal communications port -->
  <StoragePort>7000</StoragePort>
...
<ThriftAddress>127.0.0.2</ThriftAddress>
  <!-- Thrift RPC port (the port clients connect to). -->
  <ThriftPort>9160</ThriftPort>

Here are some configuration for the Fist node:
<AutoBootstrap>true</AutoBootstrap>
...
<Seeds>
      <Seed>127.0.0.1</Seed>
  </Seeds>
...
<ListenAddress>127.0.0.1</ListenAddress>
  <!-- internal communications port -->
  <StoragePort>7000</StoragePort>
...
<ThriftAddress>127.0.0.1</ThriftAddress>
  <!-- Thrift RPC port (the port clients connect to). -->
  <ThriftPort>9160</ThriftPort>


Here is the actual output when I try to start the second node:
C:\development\Cassandra\Node2\bin>cassandra.bat -f
