Do something better than UnknownScannerException
------------------------------------------------
Key: HBASE-4557
URL: https://issues.apache.org/jira/browse/HBASE-4557
Project: HBase
Issue Type: Improvement
Affects Versions: 0.90.4
Reporter: Jean-Daniel Cryans
Fix For: 0.94.0
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.
