-------------------------------------------------------------
It appears that you're appending a new cell completely? This behavior makes
sense to me, and matches the help output, but I can see how it would be
confusing.
{code}
hbase(main):001:0> help 'append'
Appends a cell 'value' at specified table/row/column coordinates.
hbase> append 't1', 'r1', 'c1', 'value', ATTRIBUTES=>{'mykey'=>'myvalue'}
hbase> append 't1', 'r1', 'c1', 'value', {VISIBILITY=>'PRIVATE|SECRET'}
{code}
Are you looking for more of an update operation?

> URL: https://issues.apache.org/jira/browse/HBASE-19582
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 2.0.0-alpha-4
> Reporter: Jean-Marc Spaggiari
>
> When appending a tag an HBase cell, they seems to not really be append be
> live their own life. In the example below, I put a cell, append the TTL, and
> we can see between the 2 scans that only the TTL append cell expires. I was
> expecting those 2 cells to become one and expire together. This can be easily
> figured by looking at the returned timestamp from the scan.
> {code}
> hbase(main):082:0> put 't1', 'r1', 'f1:c1', 'value'
> 0 row(s) in 0.1350 seconds
> hbase(main):083:0> append 't1', 'r1', 'f1:c1', '', { TTL => 5000 }
> 0 row(s) in 0.0080 seconds
> hbase(main):084:0> scan 't1'
> ROW COLUMN+CELL
>
>
> r1 column=f1:c1,
> timestamp=1513879615014, value=value
>
> 1 row(s) in 0.0730 seconds
> hbase(main):085:0> scan 't1'
> ROW COLUMN+CELL

> r1 column=f1:c1,
> timestamp=1513879599375, value=value
