------------------------------
Resolution: Invalid
> Freon uses wait/notify instead of polling to eliminate the test result errors.
> ------------------------------------------------------------------------------
>
> Key: HDDS-1703
> URL: https://issues.apache.org/jira/browse/HDDS-1703
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: test
> Affects Versions: 0.4.0
> Reporter: Xudong Cao
> Assignee: Xudong Cao
> Priority: Minor
>
> After HDDS-1532, Freon has an efficient concurrent testing framework. In the
> new framework, the main thread checks every 5s to verify whether the test is
> completed (or an exception occurred), which will eventually introduce a
> maximum error of 5s.
> In most cases, Freon's test results are at minutes or tens of minutes level,
> thus a 5s error is not significant, but in some particularly small tests, a
> 5s error may have a significant impact.
> Therefore, we can use the combination of Object.wait() + Object.notify()
> instead of polling to completely eliminate this error.
