Do it need to run 'nodetool upgradesstables' when updating from 2.0.9 to 2.1.19?
Hi, I recently upgraded my test cluster from C* 2.0.9 to 2.1.19 and I did not run 'nodetool upgradesstables' at all. Per my confirmation afterwards, everything is fine. But according to documentation at https://support.datastax.com/hc/en-us/articles/208040036-Nodetool-upgradesstables-FAQ. I need to do that. So can someone tell me if I must do 'nodetool upgradesstables' after upgrading each node from 2.0.9 to 2.1.19? Thanks. George.

You won't notice any issues (all versions of cassandra are backwards compatible at least 1 version), and sstables will be slowly migrated to the new format as you compact, but you should still run it (upgradesstables) explicitly because when it comes time to run repair/boostrap/decommission/etc, you'll need all sstables on the same/current format.

Hi! This was news to me. I had the impression that we are maintaining backwards compatibility for streaming non-upgraded sstables. Is that not the case? However, I believe it is a good idea to run upgradesstables at some point _before_ upgrading Cassandra next time to make sure there are no old sstables around before you take the next step. /pelle -Original Message- From: Jeff Jirsa [mailto:jji...@gmail.com] Sent: den 12 oktober 2017 23:11 To: Cassandra DEV Subject: Re: Do it need to run 'nodetool upgradesstables' when updating from 2.0.9 to 2.1.19?

Hi Jeff, I was under the impression that streaming in a cluster with mixed binary versions might be problematic, but as long as the cluster is on the same binary version (e.g. after a rolling upgrade), we still can have SStables in mixed data formats and streaming will work?

Two people say I’m wrong, I’ll believe it - must be imagining restrictions that don’t exist. -- Jeff Jirsa > On Oct 12, 2017, at 10:55 PM, Per Otterström > wrote: > > Hi! > > This was news to me.
