Tried running another test that did the following.
1. Started 16 compactors, 8 of which will always fails
2. Started ingest into table `ci1` which has no problems and can compact on
the good compactors.
3. Started ingest into table `ci2` which has a misconfigured iterator that
prevents any tablet on the table from compacting on any compactor.
4. Set `compactor.failure.backoff.interval=3s`
In this case the tablets in table `ci2` built up a lot of files because they
could never compact. This caused those tablets to have higher priority. Their
higher priority would cause the good compactors to get those bad tablets first
and then they would observe lots of consecutive failures. Eventually the
tablet for `ci1` would build up enough files that they would have a higher
priority and compact.
The test has been running for a bit, seeing table `ci1` with these files per
tablet stats `min:14 avg:28.47 max:35` and table `ci2` has `min:7 avg:15.22
max:35` which is never changing.
