I’m seeing multiple instances where 2 overlords thinking they are the leader and trying to update tasks at the sametime and causing errors. I’ve read https://github.com/druid-io/druid/issues/3046, seems to be related. I see this more often in 0.9.0 but I don’t recall seeing this in 0.8.3.
Is this a specific 0.9.0 bug or it exists for previous versions just not showing up for some reason.
Also see the fix https://github.com/druid-io/druid/pull/3050, will this fix the issue? Which version of Druid this is merged in?
