Major Description
HBase shell allows to specify a timestamp to get a value
- get 't1', 'r1', {COLUMN => 'c1', TIMESTAMP => ts1}
If you don't give the exact timestamp, you get nothing... so it's difficult to get the cell previous versions.
It would be fine to have a "time range" predicate based get.
The shell syntax could be (depending on technical feasibility)
- get 't1', 'r1', {COLUMN => 'c1', TIMERANGE => (start_timestamp, end_timestamp)}
