Ok... you said 2.0.10 in the original post ;-)You can't upgrade from 1.2 to
2.1.2.0.7 is the minimum. So upgrade to 2.0.17 (the latest 2.0.X) first, see
https://github.com/apache/cassandra/blob/cassandra-2.1/NEWS.txt#L244
Best,
Romain

Subject: Re: A question to updatesstables The actual error message could be
very useful to diagnose the reason. There are warnings about incompatible
formats which are safe to ignore (usually in the cache) and I have one time
seen an issue with commit log archiving preventing a startup during upgrade.
Usually there is something else broken and the version mismatch is a false
signal.

Thanks a lot. I’m a little bit of confusing. If the ‘nodetool updatesstable’
doesn’t work without Cassandra server running, and Cassandra server failed to
start due to the incompatible SSTable format, how to resolve this dilemma?

our early release we use Cassandra 1.2.10 whose SSTable is ‘ic’ format. We
upgrade Cassandra to 2.0.10 in our product release. But the Cassandra server
failed to start due to the incompatible SSTable format and the log message told
us to use ‘nodetool updatesstables’ to upgrade SSTable files. To make sure
that no negative impact on our data, I want to confirm following things about
this command before trying it: 1. Does it work without Cassandra server
running? No, it won't.
2. Will it cause data lost with this command?
It shouldn't if you followed the upgrade instructions properly
3. What’s the best practice to void this error occurs again (e.g.
upgrading Cassandra next time)?
Upgrading SSTables is required or not depending on the upgrade you're running,
basically if the SSTables layout changes you'll need to run it and not
otherwise so there's nothing you can do to avoid it
Thanks Boying
