rebalance-in fails on ec2: IP address seems to have changed. Unable to listen on 'ns_1@ec2-184-73-53-179.compute-1.amazonaws.com'.

Later saw "Resetting rebalance status since it's not really running" and "Fail Over Warning: Rebalance recommended, some data does not have the desired number of replicas!"

I tried to rebalance again and got:

Rebalance exited with reason {unexpected_exit,
{'EXIT',<0.29378.114>,
{{{{badmatch,
{error,

{error, <<"Partition 279 not in active nor passive set">>}

}},
