When upgrading from 3.4.6 (rc0 actually) to 3.5.0 (trunk as of two weeks ago actually) I got this error message:
According to Flavio Paiva Junqueira:
I think you’re right that the reconfig error is harmless, but we shouldn’t be getting it. The problem is that it is not detecting that we are in backward compatibility mode. We need to fix it for 3.5.0 and perhaps
ZOOKEEPER-1805is the right place for doing it.
