Shalin Shekhar Mangar commented on SOLR-6091:
---------------------------------------------
Would it be a good idea to include the overseer leader node name for which the
QUIT message is intended? I imagine that it'd help us catch wrong/extra QUITs
and race conditions during testing?
> Race condition in prioritizeOverseerNodes can trigger extra QUIT operations

> When using the overseer roles feature, there is a possibility of more than

> At a minimum, the prioritizeOverseerNodes should be synchronized to avoid a
