Subject AW: Migration from Cassandra 1.2.5 to Cassandra 2.0.8 with changed partitioner settings
Date Thu, 31 Jul 2014 15:16:07 GMT
Well, we ran StorageService.bulkLoad via JMX.
According to http://www.datastax.com/dev/blog/bulk-loading  this should have the same effect
and can be done on the same machine:

"Because the sstableloader uses gossip to communicate with other nodes, if launched on the
same machine that a given Cassandra node, it will need to use a different network interface
than the Cassandra node. But if you want to load data from a Cassandra node, there is a simpler
solution: you can use the JMX->StorageService->bulkload() call from said node."

You said you tried restoring a snapshot via bulk loader, did you actually run sstableloader?
