topologyStats.transferred is so much different than topologyStats.acked in storm UI

[Sa Li <sa...@gmail.com>]

Hi, All


I have been seeing in storm UI, the topo I run has such error (if this is a
error), that topologyStats.transferred is so much different than
topologyStats.acked in storm UI

any idea

Sorry for continuing this thread, but again, I am still not understanding
why acked in Topology stats are so much different with transferred/emitted
in topology stats, how do I understand the acked/transferred/emitted, I
assume they should be same or close.


thanks

AL

Hi, All

Here I attached two screenshots, as we can see from the photo, in topology
stats, the acked number is much smaller than the transferred and emitted,
the number if acked and executed are same in bolts, can someone explain
this?

thanks

Thanks for reply, but I find even I submit word count topo from storm
starter, I see the same thing, but I can see records acked in spout or bolt
(under the topology stats).

Probably you have more than one bolt receiving tuples from this bolt or
spout?
