Yuki Morishita commented on CASSANDRA-7909:
-------------------------------------------

[~kenfailbus] The purpose of this ticket is not to exit nodetool when 
notification is lost which can happen but no harm.
As the tool says, check your system.log.

> Do not exit nodetool repair when receiving JMX NOTIF_LOST

> {{nodetool repair}} prints out 'Lost notification...' and exits when JMX 
> NOTIF_LOST message is received. But we should not exit right away since that 
> message just indicates some messages are lost because "they arrive so fast 
> that they cannot be delivered to the remote client quickly enough" according 
> to 
> https://weblogs.java.net/blog/emcmanus/archive/2007/08/when_can_jmx_no.html. 
> So we should just continue to listen to events until repair finishes or 
> connection is really closed.
