We have a 3 node cluster (3 zookeeper and 3 nodes). When we restart the cluster (in no particular order) and when the flow are running, the cluster does not start and we see the attached error in the logs. This has happened to us couple of time.
Do we have to restart the cluster in any particular order? and also should we stop all the flows before we restart? please let us know.
Secondly, is there a way to track a transaction flowing through a flow from start to end out of the box? Basically I would like to know how many transaction were processed by a flow in an hour/day or week
