Looks like we're fixing another problem now. The behavior described with
VERSION=>1 is expected. If there's a problem and it keeps two version when it
should only keep one, that's a different problem, and not a correctness issue.
Maybe the second issue is already fixed by HBASE-12931?

Sorry for late reply, I will provide another patch version soon addressing
Anoop's feedback.

Are you planning on putting up another version addressing Anoop's feedback

Anoop Sam John commented on HBASE-13738:
Can not increment versionsVisible blindly. Check whether this version is
visible for the oldest scanner. That is the readPoint passed. When cur cell
seqId > smallestReadPoint, we can not increment the variable...
You can add a test with concurrent scan case also.
Add increment
Open a scanner but no next call
Add increment
Add increment
Add increment
Now next on scanner.
The later increments has to preserve the 1st cell for the old scanner.
Close scanner
Now if u again add one more increment see how many cells.

INCR old entries are getting removed from memstore when CF version is 1.
But cell upsert having some problem seems, it is retaining two entries always.
Ideally it should be one.
{ code
// versions visible to oldest scanner
int versionsVisible = 0;
while ( it.hasNext() ) {
Cell cur = it.next();
if (cell == cur) {
// ignore the one just put in
continue;
}
// check that this is the row and column we are interested in, otherwise
bail
if (CellUtil.matchingRow(cell, cur) && CellUtil.matchingQualifier(cell,
cur)) {
// only remove Puts that concurrent scanners cannot possibly see
if (cur.getTypeByte() == KeyValue.Type.Put.getCode() &&
cur.getSequenceId() <= readpoint) {
if (versionsVisible >= 1) {
code }

bq. Create an HBase table with single column family by keeping the versions=1
If you would like to see old values (cells) by raw scan, then you have to keep
the CF versions >1. If CF version is 1, we will upsert the new cell to memstore
and so can remove old entries. Pls test with >1 max_versions.
