-------------------------------------
Summary: ClientSideRegionScanner's reaction to Scan#setBatch is
not consistent between HBase versions
Key: HBASE-15274
URL: https://issues.apache.org/jira/browse/HBASE-15274
Project: HBase
Issue Type: Bug
Affects Versions: 0.98.17, 1.1.3, 1.0.3
Reporter: Youngjoon Kim
Priority: Minor
In 1.1.3, ClientSideRegionScanner calls RegionScannerImpl#next() with single
argument, so it honors Scan#setBatch(through defaultScannerContext in
RegionScannerImpl).
{code}
// 1.1.3
public class ClientSideRegionScanner extends AbstractClientScanner {
...
@Override
public Result next() throws IOException {
values.clear();
scanner.nextRaw(values);
...
{code}
\\
But in 1.0.3 and 0.98.17, ClientSideRegionScanner calls
RegionScannerImpl#next() with limit=-1, so it ignores Scan#setBatch.
{code}
// 1.0.3 and 0.98.17
public class ClientSideRegionScanner extends AbstractClientScanner {
...
@Override
public Result next() throws IOException {
values.clear();
scanner.nextRaw(values, -1); // pass -1 as limit so that we see the whole
row.
...
{code}
