> Crash loop on leaked secondary index files

> Key: ASTERIXDB-3226
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3226
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: STO - Storage
> Affects Versions: 0.9.8
> Reporter: Murtadha Makki Al Hubail
> Assignee: Murtadha Makki Al Hubail
> Priority: Major
> Labels: triaged
> Fix For: 0.9.9
>
>
> When some secondary index files are leaked after its primary is dropped, an
> NC will be in a crash loop after a restart due to the startup checkpoint task
> attempting to flush all registered indexes and we halt on missing primary
> during flush. Since there are scenarios where secondary index files can be
> leaked, we should warn rather than halt. Eventually, when all NCs complete
> their startup, the global storage cleanup will remove such indexes.
