Biju Nair created PHOENIX-3933:
----------------------------------
Summary: Start row is skipped when iterating a result set with
ScanUtil.setReversed(scan)
Key: PHOENIX-3933
URL: https://issues.apache.org/jira/browse/PHOENIX-3933
Project: Phoenix
Issue Type: Bug
Reporter: Biju Nair
{code}
ResultSet rs = statement.executeQuery("SELECT * FROM " + tableName );
QueryPlan plan =
statement.unwrap(PhoenixStatement.class).getQueryPlan();
Scan scan = plan.getContext().getScan();
while(rs.next()) {
LOG.debug("******** "+rs.getInt(1));
}
{code}
This section of the code returns
{code}
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 0
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 1
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 2
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 3
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 4
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 5
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 6
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 7
[main] org.apache.phoenix.end2end.ReverseScanTest(126): ******** 8
{code}
If the {{scan}} is set to reverse the start and stop key is set to 4 & 8 the
resulting result set doesn't seem to include 8 in the result which is different
from the HBase scan when reversed.
{code}
ScanUtil.setReversed(scan);
scan.setStartRow(PInteger.INSTANCE.toBytes(4));
scan.setStopRow(PInteger.INSTANCE.toBytes(8));
rs = new PhoenixResultSet(plan.iterator(), plan.getProjector(),
plan.getContext());
while(rs.next()){
LOG.debug("**rev*** "+rs.getInt(1));
}
{code}
the result is
{code}
org.apache.phoenix.end2end.ReverseScanTest(136): **rev*** 7
org.apache.phoenix.end2end.ReverseScanTest(136): **rev*** 6
org.apache.phoenix.end2end.ReverseScanTest(136): **rev*** 5
org.apache.phoenix.end2end.ReverseScanTest(136): **rev*** 4
