Yonik Seeley commented on SOLR-13815:
-------------------------------------
OK, I've confirmed that this test sometimes fails on master (normally a single
doc missing.)
The test itself is pretty simple, so this may be a real bug that is relatively
easy to trigger. I didn't see any exceptions in the failing test run either
(before the failed assertion)
Next step is to enhance the test to figure out what documents are missing to
aid in debugging.

> 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.
