Section 5.7.3 of the HBase book displays a scan operation:
HTable htable = ... // instantiate HTable
Scan scan = new Scan();
scan.addColumn(Bytes.toBytes("cf"),Bytes.toBytes("attr"));
scan.setStartRow( Bytes.toBytes("row"));
scan.setStopRow( Bytes.toBytes("row" + new byte[] {0})); // note: stop key !=
start key
for(Result result : htable.getScanner(scan)) {
// process Result instance
}
Can someone explain why the stop key is "row" plus an empty byte? The
example says it should return all rows that start with "row" however
wouldn't this only return a row with the exact row key of "row"?
"row" < "row\000" => true
"row\000" < "row1" => false
Shouldn't the example be "row" + new byte[] {255}?
"row1" < "row\255" => true
Can someone please clarify?
