Yes, I'm a fan of running sstableloader on a server that is not one of the nodes in the cluster. You can maximise the throughput by running multiple instances of sstableloader loading SSTables from separate sources/filesystems. My suspicion is that the failed connection to the nodes is due to the SSL options so check that you've specified the truststore/keystore correctly. Cheers! >
