Resolution: Incomplete
> Do something better than UnknownScannerException
> ------------------------------------------------
>
> Key: HBASE-4557
> URL: https://issues.apache.org/jira/browse/HBASE-4557
> Project: HBase
> Issue Type: Improvement
> Components: Usability
> Affects Versions: 0.90.4
> Reporter: Jean-Daniel Cryans
> Priority: Major
> Labels: beginner
>
> UnknownScannerException is a plague, there's no reason we should not at least
> try to create a new scanner. If that fails again, maybe try automatically
> setting a lower scanner caching (if possible and with proper loggin) and
> retry again.
