Unable to change Kafka property num.network.threads from default 3.

[#1]

We use Cloudera Enterprise 5.7.1 and Cloudera Manager 5.8.

I am trying to increase the Kafka's num.network.threads property value from 3 to 8. But I am unable to find it in Cloudera Manager Configuration page for Kafka.

Any pointers on how to change this value ?

Thanks,

Vivek

Assuming you want to set this on Brokers, you may append it in the syntax shown below into the UI field of CM -> Kafka -> Configuration -> "Kafka Broker Advanced Configuration Snippet (Safety Valve) for kafka.properties":

num.network.threads=8

For understanding these fields better, please read our Custom Configuration CM feature documentation at http://www.cloudera.com/documentation/enterprise/latest/topics/cm_mc_config_snippet.html

Thank you for a quick response. I will make the change and post if I have any issues.
