Subject RE: upgrade from 1.0.12 to 1.1.12

Yes, run upgradesstables on all nodes - unless you already force major compactions on all tables.
I run them on a few nodes at a time to minimize impact to performance. The upgrade is not
complete until upgradesstables completes on all nodes. Then you are safe to resume any streaming
operations (repairs and bootstraps).

hmm... okay.

one more question
https://github.com/apache/cassandra/blob/cassandra-1.1.12/NEWS.txt  I upgraded directly to
1.1.12 , do I need to run nodetool upgradesstables as stipulated in version 1.1.3 ?
