> Arya Goudarzi reports:
> 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:

> Now I ran:

> 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:
