In this case, it seems more likely CHANGES.txt will be correct, since it is maintained *at time of commit*, whereas JIRA fix versions can be forgotten to be maintained. On Tue, Sep 9, 2014 at 7:07 AM, Robert Coli wrote: > On Mon, Sep 8, 2014 at 2:56 PM, Peter Haggerty > wrote: > >> When the CHA

When the CHANGES file shows an issue as being in a particular release but the JIRA for the issue shows a different version in "Fix Versions" which one is right? All four of these are listed in 2.0.10 in the CHANGES file: https://github.com/apache/cassandra/blob/cassandra-2.0/CHANGES.txt https://i

Thrift is still present in the 2.0 branch as well as 2.1. Where did you see that it's deprecated? Let me elaborate my earlier advice. Shuffle was removed because it doesn't work for anything beyond a trivial dataset. It is definitely "more risky" than adding a new vnode enabled DC, as it does n

2014-09-08 Thread Jonathan Haddad
I believe shuffle has been removed recently. I do not recommend using it for any reason. If you really want to go vnodes, your only sane option is to add a new DC that uses vnodes and switch to it. The downside in the 2.0.x branch to using vnodes is that repairs take N times as long, where N is

I have setup Cassandra into VPC with the EC2Snitch and it works without issues. I didn't need to do anything special to the configuration. I have created instances in 2 availability zones, and it automatically picks it up as 2 different data racks. Just make sure your nodes can see each other in th

Dear Colleagues: I need to move Cassandra from EC2 classic into VPC. What I was thinking is that I can create a new data center within VPC and rebuild it from my existing one (switching to vnodes while I am at it). However, I don't understand how the ec2-snitch will deal with this. Another i
