Subject upgrading 1.1.x to 1.2.x via sstableloader
Date Wed, 03 Apr 2013 17:23:36 GMT
Does anyone knows what is the best process to put data from cassandra 1.1.x
(1.1.7 to be more precise) to cassandra 1.2.3 ?

I am trying to use sstableloader and stream data to a new cluster but I get.

ERROR [Thread-125] 2013-04-03 16:37:27,330 IncomingTcpConnection.java (line

I've changed Murmur3Partitioner to RandomPartitioner already and I've
noticed I am not able to use 1.1.7's sstableloader so I copied sstables to
new nodes and tried doing it locally on cassandra 1.2.3, but it seems
protocol versions do not match (see error above)

The reason why I want to use sstableloader is that I have different number
of nodes and would like to avoid using rsync and then repair/cleanup of
excessive data.

Thanks!
