Hello happy metron users,
I've a Metron cluster based on Hortonworks CP, and I've setup Kerberos on the
top of it, as you all probably have done since we deal with security :)
It seems that everything is working fine, Kerberos, ranger,... but I'm facing
an issue regarding the overall throuput.
I feed my cluster with Nifi, here is what I do:
Test 1:
- Send 2 lines of logs to Kafka sensor topic with Nifi
- Use Kafka CLI consumer to read messages from sensor topic: response
is immediate
- Use kafka CLI consumer to read messages from enrichment topic:
messages are coming after nearly 20 s
Test 2:
- Send 200 lines of logs to Kafka sensor topic with Nifi
- Use Kafka CLI consumer to read messages from sensor topic: response
is immediate
- Use kafka CLI consumer to read messages from enrichment topic: some
messages are coming immediately, but it seems they come 10 by 10 (nearly), with
many seconds between each flow
It's probably related to Storm configuration, but I don't know where to go now.
I've tried to change various parameters like topology.max.spout.pending
(currently set to 500), but no improvement
Thanks for your help
Stéphane
