> RoundRobinResultIterator uses "hbase.client.scanner.caching" to fill caches
> in parallel for all scans, but by setting Scan.setCaching() in
> PhoenixInputForrmat(phoenix-hive), RoundRobinResultIterator doesn't work
> correctly, because if Scan have cache size by setCaching(), HBase uses cache
> size from Scan.getCaching() to fill cache, not
> "hbase.client.scanner.caching", and RoundRobinResultIterator scans the table
> in parallel to fill caches every "hbase.client.scanner.caching", resulting in
> unintended parallel scan operation, this causes scan performance degradation.
