----------------------------------
Summary: ScanUtil#unsetReversed doesn't seem to unset reversal of
Scan
Key: PHOENIX-3921
URL: https://issues.apache.org/jira/browse/PHOENIX-3921
Project: Phoenix
Issue Type: Bug
Reporter: Biju Nair
Created a new iterator with a {{scan}} object set to be non reversed using
{{ScanUtil.unsetReversed(scan)}}. But the iteration moves in the reverse order.
{{BaseResultIterators.java}} has the condition check
{code}
boolean isReverse = ScanUtil.isReversed(scan);
{code}
Looking at
[ScanUtil.java|https://github.com/apache/phoenix/blob/2cb617f352048179439d242d1165a9ffb39ad81c/phoenix-core/src/main/java/org/apache/phoenix/util/ScanUtil.java#L609]
{{isReversed}} method is defined as
{code}
return scan.getAttribute(BaseScannerRegionObserver.REVERSE_SCAN) != null;
{code}
do we need to change the condition check to compare to {{PDataType.TRUE_BYTES}}
The current logic will return {{isReversed}} as {{true}} whether the
{{BaseScannerRegionObserver.REVERSE_SCAN}} attribute is set to
{{PDataType.TRUE_BYTES}} or {{PDataType.FALSE_BYTES}} which corresponds to
values set in {{setReversed}} and {{unsetReversed}} methods.
