Hi,

Please confirm if this is an issue and should be reported or I am doing something wrong. I could not find anything relevant on JIRA:

Playing with 0.7 nightly (today's build), I setup a 3 node cluster this way:

 - Added one node;
 - Loaded default schema with RF 1 from YAML using JMX;
 - Loaded 2M keys using py_stress;
 - Bootstrapped a second node;
 - Cleaned up the first node;
 - Bootstrapped a third node;
 - Cleaned up the second node;

I got the following ring:

Address       Status     Load          Range                                      Ring
                                       154293670372423273273390365393543806425

10.50.26.134  Up         234.8 MB      111685517405103688771527967027648896391    |   |

Now I ran:

nodetool --host 10.50.26.132 loadbalance

It's been going for a while. I checked the streams  

nodetool --host 10.50.26.134 streams
Mode: Normal
Not sending any streams.
Streaming from: /10.50.26.132
   Keyspace1: /var/lib/cassandra/data/Keyspace1/Standard1-tmp-d-3-Data.db/[(0,22206096), (22206096,27271682)]

   Keyspace1: /var/lib/cassandra/data/Keyspace1/Standard1-tmp-d-6-Data.db/[(0,366336059), (366336059,450095320)]

nodetool --host 10.50.26.132 streams
Mode: Leaving: streaming data to other nodes
Streaming to: /10.50.26.134
   /var/lib/cassandra/data/Keyspace1/Standard1-d-48-Data.db/[(0,366336059), (366336059,450095320)]
Not receiving any streams.

These have been going for the past 2 hours.

I see in the logs of the node with 134 IP address and I saw this:

INFO [GOSSIP_STAGE:1] 2010-06-22 16:30:54,679 StorageService.java (line 603) Will not change my token ownership to /10.50.26.132

So, to my understanding from wikis loadbalance supposed to decommission and re-bootstrap again by sending its tokens to other nodes and then bootstrap again. It's been stuck in streaming for the past 2 hours and the size of ring has not changed. The log in the first node says it has started streaming for the past hours:

Nothing more after this line.

Am I doing something wrong?
