ctubbsii opened a new issue, #5577:
URL: https://github.com/apache/accumulo/issues/5577
> I think the issue in #5531 was revealed by the presence of this test, but
this test, trying to simulate a portion of a previous version's state to
exercise a specific upgrade step on a live system is inherently flaky, because
it breaks core assumptions about the state of the built-in tables on a running
system. That has consequences in other areas of the code than just the balancer
race condition that was identified in #5531. I still think this test should be
deleted, but agree that we need a new, more narrow, test to check for that race
condition that was identified in #5531.

I believe the test discussed in #5566 wrote to the accumulo.root table when
the metadata table changes to delete the accumulo.scanref table were flushed,
resulting in a new RFile for the accumulo.metadata table. A new test should do
something similar by causing changes to the root table, but should not do so by
attempting to remove a built-in table, which breaks other assumptions on the
live system.
