| Subject | Re: Whole topology restarts when a worker crash |
| Date | Wed, 02 Apr 2014 11:18:36 GMT |
OK, seems all this was a misunderstanding of how Trident works. I allowed 2 supevisor slots on each machine, but kept 1 worker per machine. When I killed machine A, worker from machine A took the unused slot on machine B. First worker slot didn't restarted. I then restarted machine A and rebalanced the topology. Only one worker was moved. This is the behaviour I expected. To put it in a nutshell : Always reserve empty slots for fault-tolerance. Thanks again for the time you took Anuj :) | |
