Subject Migration from Cassandra 1.2.5 to Cassandra 2.0.8 with changed partitioner settings
Date Tue, 29 Jul 2014 12:30:00 GMT
We are planning to migrate data from a Cassandra 1.2.5 to a new Cassandra
2.0.8 cluster with changed partitioner settings (1.2.5:
org.apache.cassandra.dht.RandomPartitioner,  2.0.8:
org.apache.cassandra.dht.Murmur3Partitioner). Restoring a snapshot via
BulkLoader fails with error message 
SSTableReader.java (line 233) Cannot open
/opt/database/apache-cassandra/xxx: partitioner
org.apache.cassandra.dht.RandomPartitioner does not match system partitioner
org.apache.cassandra.dht.Murmur3Partitioner. 
When trying to use the cqlsh COPY command we get rpc_timeout errors on
export (see also
http://www.datastax.com/dev/blog/simple-data-importing-and-exporting-with-cassandra)
and also TTL settings are not exported.
So what's the proposed tool/solution for transfering/migrating data in this
case?
