Dan Smith created GEODE-8522:
--------------------------------
Summary: Locators log full stack traces of exceptions at info
level during normal startup
Key: GEODE-8522
URL: https://issues.apache.org/jira/browse/GEODE-8522
Project: Geode
Issue Type: Bug
Reporter: Dan Smith
It's normal to configure multiple locators that all refer to each other's
addresses. When starting up, the first locator that starts up will always log
an exception failing to talk to other locators.

We shouldn't log full stack trace exceptions for something that is normal part
of the startup process, because it makes it harder to search for errors.
This is coming from this line in the code, which was switch from debug to info
in the last year:
