Yonik Seeley commented on SOLR-13815:
-------------------------------------
bq. the shard state is coming from the clusterstate which is a single znode
updated atomically.
Oops, of course! I was down in the JSON so much I lost sight of the fact that
it's a single znode.

> This issue is to investigate potential data loss during a "live" split (i.e.
> split happens while updates are flowing)
> This was discovered during the shared storage work which was based on a
> non-release branch_8x sometime before 8.3, hence the first steps are to try
> and reproduce on the master branch without any shared storage changes.
