Motivation
We are frequently getting 500 on
pulsar-admin topics list <ns>
cli command. It happens becausepulsar-admin topics
rest-api internally usespulsar-admin
to get list of non-persistent topics.PulsarAdmin-HttpClient
crates persistent connection but it doesn't perform auto-cert refresh so, if cert is expired and reconnection happens then broker always gets 500 when it usespulsar-admin
internally due to invalid certs.Modification
Add Capability in HttpClient to perform auto-cert refresh to avoid any tls handshake failure.
