Ted Yu commented on HBASE-16886:
--------------------------------
{code}
161 localStartKey = this.scan.getStartRow();
162 isFirstLocatedRegion = true;
{code}
There is regionChanged flag already. See if it is possible to combine the two
flags.
Add javadoc for SmallReversedScannerCallable.
{code}
60 "Does hbase:meta exist hole? Couldn't get regions for the
range from "
{code}
Change the wording from question to description: Hole may exist ...
SmallScannerCallable is in ClientSmallScanner. Can the new class be defined in
ClientSmallScanner as well ?
The prepare method overlaps with that from ReversedScannerCallable. Is it
possible to extract common code ?
Same with locateRegionsInRange and its ReversedScannerCallable counterpart.
> hbase-client: scanner with reversed=true and small=true gets no result
