how to debug tuple failures

[Anshul Mittal <an...@pinterest.com>]

Hi,
I am running a storm topology with the following configuration:
*Storm : 0.8.2*
*Kafka : 0.7.2*
*Storm Kafka Spout : 0.8.0-wip4*

I am observing that after some time, the topology enters a weird state and
starts retrying a bunch of tuples. I want to see what exact failure causes
the topology to retry tuples. Is there a place where the storm kafka spout
emits tuple failures? My logs show no error in the bolts.

Thanks!
Anshul

I had encountered such an
issue<http://mail-archives.apache.org/mod_mbox/incubator-storm-user/201403.mbox/%3CCAHhx-G%2B6Hhh2d9RzQwWrUT2wyVvrSyZCQLNm21GL5307b8tZuA%40mail.gmail.com%3E>earlier
on version 0.9.0.1 but did not get much help to resolve it.
Try to tune the topology.max.spout.pending value based on the latency
metrics from storm UI.
