Zheng Wang commented on HBASE-22710:
------------------------------------
Maybe the problem is here.
{code:java}
ScanQueryMatcher.java
getTrackers()
{
...
if (userScan != null) {
if (userScan.isRaw()) {
resultMaxVersion = userScan.getMaxVersions();
} else {
resultMaxVersion = Math.min(userScan.getMaxVersions(),
scanInfo.getMaxVersions());
}
//here
maxVersionToCheck = userScan.hasFilter() ? scanInfo.getMaxVersions() :
resultMaxVersion;
}
...
}{code}
The scanInfo.getMaxVersions() return 1,it is from the column family 's define,
the resultMaxVersion is 2,it is from scan requset.
But i don't understand why the filter should effect maxVersion?
> Wrong result in one case of scan that use raw and versions and filter
> together

>
> create 'testScanRaw',\{NAME => 'f', VERSIONS => 1}
>
> put 'testScanRaw','r1','f:q','1'
> put 'testScanRaw','r1','f:q','2'
> put 'testScanRaw','r1','f:q','3'

> hbase(main):005:0> scan 'testScanRaw',\{RAW => true, STARTROW => 'r1',

> ROW COLUMN+CELL
> r1 column=f:q, timestamp=1563430154757, value=3
> r1 column=f:q, timestamp=1563430153120, value=2

> BTW,the result is right in hbase1.2.
