Istvan Toth commented on HBASE-28662:
-------------------------------------
The problem is in
org.apache.hadoop.hbase.rest.ScannerResource.getScannerInstanceResource(String)
, where we return a dummy scanner instead of an error code when the client
requests a non-existent scanner.
> Removing missing scanner via REST should return 404
> ---------------------------------------------------

> URL: https://issues.apache.org/jira/browse/HBASE-28662
> Project: HBase
> Issue Type: Bug
> Components: REST
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Minor
>
> We do not handle the case when the user is trying to remove a missing
> scanner, and let an NPE bubble up to Jersey.
> We should check or catch the error and return 404 instead.
