问题
I have compiled a topology. In nimbus status I have some sequence of numbers like this
executor->start-time-secs <[2 2]1389244616,[3 3]1389244616,[4 4]1389244616,[5 5]1389244616,
What do the sequence numbers mean?
回答1:
In the sequence
:executor->start-time-secs <[2 2]1389244616,[3 3]1389244616,[4 4]1389244616,[5 5]1389244616,
[2 2],[3 3],[1 1] - represents the node. These node are assigned in :executor->node+port{} as given below which is further used by topology
:executor->node+port {[3 3] ["7693b2c4-478b-4412-a351-c558f855374a" 4], [2 2] ["7693b2c4-478b-4412-a351-c558f855374a" 4], [1 1] ["7693b2c4-478b-4412-a351-c558f855374a" 4]}
1389244616 - represents the current timestamp when you are running the topology.
as 1389244616 is equal to 9-Jan-2014 @ 5:16:56am UTC
