Motivation

Use INFO log level when a successful event happens. The Pulsar Coding Guide mentions that WARN is only for "bad" events. https://pulsar.apache.org/en/coding-guide/#logging-levels

WARN and ERROR indicate something that is BAD. Use WARN if you aren't totally sure it is bad, and ERROR if you are.

Modifications

• Switch warn to log in the java client
