> Implement eviction logic for scanners in Rest APIs to prevent scanner leakage
> -----------------------------------------------------------------------------
>
> Key: HBASE-28504
> URL: https://issues.apache.org/jira/browse/HBASE-28504
> Project: HBase
> Issue Type: Improvement
> Components: REST
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> The REST API maintains a map of _ScannerInstanceResource_s (which are
> ultimately tracking Scanner objects).
> The user is supposed to delete these after using them, but if for any reason
> it does not, then these objects are maintained indefinitely.
> Implement logic to evict old scanners automatically.
