Subject Exception when setting tokens for the cassandra nodes
Date Mon, 29 Apr 2013 16:23:29 GMT
Hi,
I am testing out Cassandra 1.2 on two of my local servers. But I face
problems with assigning  tokens to my nodes. When I use nodetool to set
token, I end up getting an java Exception.
My test setup is as follows,
Node1: <local ip 1> (seed)
Node2: <local ip 2> (seed)

Since I have two nodes, i calculated the tokens as 0 and 2^127/2
= 85070591730234615865843651857942052864. I was able to set token 0 for my
first node using nodetool move 0 , but when i am trying to
set 85070591730234615865843651857942052864 for my second node,
it throws a main UndeclaredThrowableException. Full stack is attached
bellow.

user@server~$ nodetool move 85070591730234615865843651857942052864
