Search before asking

• I searched in the issues and found nothing similar.

Read release policy

• I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

Version

3.3.1 - server only, running on Amazon Linux 2

Minimal reproduce step

• Setup etcd cluster with mTLS auth enabled
• Setup pulsar-broker with etcd configured for mTLS

example configuration:

# broker.conf:
metadataStoreConfigPath: /pulsar/metadata-config/etcd.yaml
metadataStoreUrl: "etcd:https://pulsar-etcd-headless:2379"
configurationMetadataStoreUrl: "etcd:https://pulsar-etcd-headless:2379"

# /pulsar/metadata-config/etcd.yaml
useTls: true
tlsProvider: "OPENSSL"
tlsTrustCertsFilePath: "/pulsar/etcd-cert/ca.crt"
tlsKeyFilePath: "/pulsar/etcd-cert/tls.key"
tlsCertificateFilePath: "/pulsar/etcd-cert/tls.crt"
authority: ""

What did you expect to see?

Working mTLS connection to etcd.

What did you see instead?

The mentioned PR is the last time, when jetcd has been touched.

Anything else?

It works fine on v3.3.0 with the above config. I'm willing to submit a PR, but I don't know how to fix it :|
