Paulo Motta commented on CASSANDRA-12008:
-----------------------------------------

In this specific case it seems the streaming failed due to low {{streaming_socket_timeout}} value. We just found out our previous default of 1 hour was too low, and raised that to 24 hours on CASSANDRA-11840, on 3.0.7. Could you try increasing that and see if it helps with failed decommissions?

> We're dealing with large data sets (multiple terabytes per node) and sometimes we need to add or remove nodes. These operations are very dependent on the entire cluster being up, so while we're joining a new node (which sometimes takes 6 hours or longer) a lot can go wrong and in a lot of cases something does.
> It would be great if the ability to retry streams was implemented.
> Example to illustrate the problem :
> {code}
> 03:18 PM   ~ $ nodetool decommission
> error: Stream failed
