Subject: [EXTERNAL] Common for storm UI to not show emits?


​I confirmed from the logs that all spouts were emitting and ack'ing. Strangely, the UI
doesn't show it. Moreover, Spout 1, 2 and 3 show no emissions but there are ack's. Is it common
for Storm to show results like this?
Here, 10 spouts emit to a bolt (which run as 4 tasks) via fieldsGrouping. The bolt ack's.
After each spout receives 20 ack's from the bolt, the spout emits to the bolt again using
