While debugging:
- As part of PulsarService start, it fails while reading nic speed ("/sys/class/net/<nic>/speed") with "java.io.IOException: Invalid argument" exception.
- cat on same nic path fails for me. (my Wifi nic speed do not have specific value)
I believe Pulsar CI Github action is running on VM where nic speed is set and test run is able to read nic speed of a VM where test-suite is running. This failure can only be observed if test is running on machine/VM where nic speed is not set.
Possible fix :
- Since, The test is asserting on metadata values such as Topic, Tenant, Namespace and nothing related to underlying machine resource limits so, setting "loadBalancerOverrideBrokerNicSpeedGbps=2" as part of broker test config (standalone_no_client_auth.conf) would fix this.
I am new to this project. So, can someone confirm the same? Happy to know if I have missed something.
