Shalin Shekhar Mangar commented on SOLR-8069:
---------------------------------------------
bq. Hmmm, reading the code now I'm not sure it's doing exactly the right thing
since it calls getLeaderSeqPath, which just takes the current ElectionContext
from electionContexts, which isn't necessarily the one the node had when it
decided to mark someone else down, right? Shalin Shekhar Mangar thoughts?
Right, we should acquire the leader sequence path at the beginning of the
update instead of so late in the game. I believe Mark's patch has the same
problem but it is somewhat diluted by checking against CloudDescriptor.isLeader.

> I've seen this twice now. Need to work on a test.
> When some issues hit all the replicas at once, you can end up in a situation
> where the rightful leader was put or put itself into LIR. Even on restart,
> this rightful leader won't take leadership and you have to manually clear the
> LIR nodes.
> It seems that if all the replicas participate in election on startup, LIR
> should just be cleared.
