> FileSystemTimelineReaderImpl vulnerable to race conditions
> ----------------------------------------------------------
>
> Key: YARN-11916
> URL: https://issues.apache.org/jira/browse/YARN-11916
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: timelineserver
> Affects Versions: 3.4.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Labels: pull-request-available
>
> Yarn timelineserver FileSystemTimelineReaderImpl implementation does atomic
> updates via: copy, append, rename. This gives it bad scalability and
> concurrent calls will lose data.
> has bad concurrency on write and will lose updates. And its scalability
> Not plans to fix what was just the PoC of the v2 API, just
> * update javadocs
> * warn on startup that people should stop it.
> * do some other hardening while there, and test cleanup
> This code is @Private/@Unstable. Maybe we can move it into the -test jar.
> Nobody will complain.
