Subject how long to wait for action (waiting for bootstrap token)
Date Wed, 15 Sep 2010 10:09:35 GMT
Hi,

I would like to extend our cassandra system by another node. It contains about 800GB data
right now. I have set up another host and installed cassandra (both 0.6.3). The new cassandra
node starts up and contacts the first to receive "load info" and then tries to receive the
bootstrap token:

DEBUG 11:35:12,277 attempting to connect to /10.0.1.1
 INFO 11:35:12,975 Node /10.0.1.1 is now part of the cluster

nodetool on this new host gives me:

./bin/nodetool -h localhost streams
Mode: Joining: getting bootstrap token
Not sending any streams.
Not receiving any streams.

I'd like to know how long it can take until the bootstrap token is received. I guess we may
have about 500 million keys on the seed node.
What I was wondering too, is the short host is dead and host is UP notice. I have no idea
where this comes from. The seed node says operation mode is normal.

Thanks,

	Leo.
