Thank you! I made my comments in the JIRA. Sean Durity – Lead Cassandra Admin From: Jeff Jirsa [mailto:jeff.ji...@crowdstrike.com] Sent: Monday, December 14, 2015 3:25 PM To: user@cassandra.apache.org Subject: Re: Issues on upgrading from 2.2.3 to 3.0
https://issues.apache.org/jira/browse/CASSANDRA-10745 GPFS seems like it SHOULD be easier to package and distribute in most use cases… From: "sean_r_dur...@homedepot.com<mailto:sean_r_dur...@homedepot.com>" Reply-To: "user@cassandra.apache.org<mailto:user@cassandra.apache.org>" Date: Monday, December 14, 2015 at 11:56 AM To: "user@cassandra.apache.org<mailto:user@cassandra.apache.org>" Subject: RE: Issues on upgrading from 2.2.3 to 3.0 Is there a JIRA for the discussion of dropping PropertyFileSnitch? That is all that we use, and it is much easier to package and distribute than GossipingPropertyFileSnitch. I would vote against dropping the more useful PropertyFileSnitch. Sean Durity – Lead Cassandra Admin From: Paulo Motta [mailto:pauloricard...@gmail.com] Sent: Thursday, December 03, 2015 7:04 AM To: user@cassandra.apache.org<mailto:user@cassandra.apache.org> Subject: Re: Issues on upgrading from 2.2.3 to 3.0 You can migrate from the RackInferingSnitch to PropertiesFileSnitch by populating the cassandra-topology.properties with the same rack/dc assignments of the previous snitch (what you can't change is the assignment, but you can change snitches if you maintain the same assignments as before). For example, if you were using using the RackInferingSnitch before, an equivalent configuration on the PropertiesFileSnitch is: IP=DC:RACK 175.56.12.105=56:12 (3rd octet is DC, 2nd is RACK on RackInferingSnitch) 175.56.13.200=56:13 175.54.35.197=54:35 120.54.24.101=54:24 There is a chance the PropertiesFileSnitch is deprecated in the near future, so it's preferable to use the GossipingPropertyFileSnitch which is also simpler to configure. 2015-12-02 23:30 GMT-08:00 Carlos A <nando....@gmail.com<mailto:nando....@gmail.com>>: Bryan, thanks for replying. I had that figured out already few days ago. The issue was that the snitch method was also changed on the configuration hence the problem. Now, if you change from rackInferingSnitch to PropertiesFileSnitch it will not run as the data has to be migrated. Is that correct? Or do you have the change the replication class on the keyspace? Putting back to rackInferingSnitch worked just fine. On Wed, Dec 2, 2015 at 6:30 PM, Bryan Cheng <br...@blockcypher.com<mailto:br...@blockcypher.com>> wrote: Has your configuration changed? This is a new check- https://issues.apache.org/jira/browse/CASSANDRA-10242. It seems likely either your snitch changed, your properties changed, or something caused Cassandra to think one of the two happened... What's your node layout?

Please fix the snitch or decommission and rebootstrap this node. It asks to "Please fix the snitch or decommission and rebootstrap this node" If none of the nodes can go up, how can I decommission all of them? Doesn't make sense. Any suggestions?
