Subject: [PATCH] RabbitMQ: Forget node before 2nd joining attempt
|
||
|
|
|
||
|
|
If a first attempt at joining an existing cluster has failed and we
|
||
|
|
resort to wiping the local RabbitMQ data, make sure we also request the
|
||
|
|
local node to be forgotten from the existing cluster before we make the
|
||
|
|
join attempt, otherwise the node will be rejected.
