Description

we use HBase PerformanceEvaluation tools to test HBase,when using scan interface to test ,we found that scanTest said that it read all row ,but after read the source code ,we foud it just read the the first row and return .and after making a comparison with randomSeekScanTest,it read all row ,so we think it is a bug .

void testRow(final int i) throws IOException {
if (this.testScanner == null) {
Scan scan = new Scan(format(opts.startRow));
scan.setCaching(opts.caching);
if (opts.addColumns)

{ scan.addColumn(FAMILY_NAME, QUALIFIER_NAME); }

else

{ scan.addFamily(FAMILY_NAME); }

if (opts.filterAll)

{ scan.setFilter(new FilterAllFilter()); }

this.testScanner = table.getScanner(scan);
}
Result r = testScanner.next();
updateValueSize(r);
}
