Kevin Wu updated KAFKA-19489:
-----------------------------
Description:
The storage tool currently allows for setting both the static voters config
({{{}controller.quorum.voters{}}}) and attempting to format with one of
{{--standalone, --initial-controllers, --no-initial-controllers}} on a
controller, but instead it should throw an exception. This is because setting
{{controller.quorum.voters}} itself is formatting the voter set.
Setting {{controller.quorum.voters}} while trying to format with a --standalone
and {{-no-initial-controllers}} setup can result in 2 voter sets. For example,
in a three node setup, the two nodes that formatted with
--no-initial-controllers could form quorum with each other since they have the
static voter set, and the {{-standalone}} node would ignore the config and read
the voter set of itself from its log, forming its own quorum of 1.
