I have Cassandra Datastax 2.2.3 cluster (only one node) and as a test I'm adding a new node. After successfully adding the new node and starting it with bootstrap=false, I'm trying to rebalace it with nodetool repair.
However, this error pops up in logs of the old node:

and the repair fails:

I've tried running nodetool repair -seq - result is the same.
Questions?
- How much memory does nodetool repair need? How to check it?
- How can I rebalance the ring now? Is there any way to trigger repair step by step?
- If not, can I add "virtual" RAM (maybe as swap), increase heap and trigger the repair?
