Description

When Nifi Registry is configured with TLS, health checks fail:

When checking the health of a tls enabled Nifi Registry, only the trust store parameters are required. The following Keystore related parameters are not required:

~~kp,~~-keyPassword <arg> The key password of the key store being used
~~ks,~~-keyStore <arg> The key store to use
~~ksp,~~-keyStorePassword <arg> The password of the key store being used
~~kst,~~-keyStoreType <arg> The type of key store being used (PKCS12 or JKS) (default: JKS)

The following patch allows the health check to operated as expected:

It may be worth noting that the JKS used by Nifi, Nifi Registry, etc. contains a JKS password, but not a key password.

In any case, a keystore isn't required by this utility to do an http get/check https endpoint in any case I can see.

This issue only manifest in cases where Nifi Registry has tls/ssl enabled. If tls/ssl is not enabled on the Nifi Registry, a different branch is used to check Nifi Registry's http endpoint availability in:
