Use SSTableloader it comes with Cassandra and is designed for moving data between clusters and is far simpler than sqoop. it "should" even work with a schema change like you described (changing columns). It would probably/definitely break if you were dropping tables.
Mind you I've never tried sstableloader while schema changes were occurring so happy to be wrong. On 14 April 2015 at 05:40, Prem Yadav <ipremya...@gmail.com> wrote: > Look into sqoop.
