Philippe Laflamme commented on HBASE-19582:
-------------------------------------------
This is also a problem when trying to extend the TTL:
{code}hbase(main):001:0> truncate 't1'
Truncating 't1' table (it may take a while):
- Disabling table...
- Truncating table...
0 row(s) in 4.2470 seconds
hbase(main):002:0> put 't1', 'r1', 'f1:c1', 'v1', {TTL=>5000}
0 row(s) in 0.1180 seconds
hbase(main):003:0> scan 't1'
ROW
COLUMN+CELL
r1
column=f1:c1, timestamp=1513884993222, value=v1
1 row(s) in 0.0250 seconds
hbase(main):004:0> append 't1', 'r1', 'f1:c1', '', {TTL => 600000}
0 row(s) in 0.0190 seconds
hbase(main):005:0> scan 't1'
ROW

> Key: HBASE-19582
> 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
