Summary: HBase PerformanceEvaliation tools 's scan test just get
the first value and return
Key: HBASE-18745
URL: https://issues.apache.org/jira/browse/HBASE-18745
Project: HBase
Issue Type: Bug
Components: scan, test
Affects Versions: 1.1.12, 1.2.6
Environment: centos 6.8;
java 1.8.0_102;
Reporter: maxwellguo
Priority: Minor
Fix For: 2.0.0
h5. 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);
}
