Alan Woodward resolved LUCENE-8714.
-----------------------------------
Resolution: Fixed
Fix Version/s: master (9.0)
> BaseNormsFormatTestCase should not use NoMergePolicy
> ----------------------------------------------------

> Key: LUCENE-8714
> URL: https://issues.apache.org/jira/browse/LUCENE-8714
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Alan Woodward
> Assignee: Alan Woodward
> Priority: Major
> Fix For: master (9.0)

> Attachments: LUCENE-8714.patch
>
>
> Jenkins found a test failure that stems from a combination of LimitHandleFS
> and NoMergePolicy. There's no particular reason for BaseNormsFormatTestCase
> to prevent merges, so we should just remove this IndexWriteConfig setting in
> the test.

> (when running all methods of that test w/that seed, many of them fail _after_

> failure?)
> Also: this test is called \{{TestLucene70NormsFormat}} but it has \{{new
> Lucene80Codec()}} hardcoded in it ... which seems like a pretty big WTF?
