Thanks Suraj. I looked at the code but it looks like the logic is not
self-contained, particularly for the way hbase works with search for a
specific version using TimeRange.

You may need to setup your Eclipse workspace and search using
references etc.To get started, this is one class that uses TimeRange
based matching ...
org.apache.hadoop.hbase.regionserver.ScanQueryMatcher
Also - Get is internally implemented as a Scan over a single row.
Hope this gets you started.
Hi St.Ack:
Can you tell me which source code is responsible for the logic. The source code
in the get and scan doesnt provide an indication of how the setTimeRange works.

Somebody will correct me if I'm wrong, but I think that for your
example, you should use setTimeRange(0, 5) and setMaxVersion(1). It's
my understanding that those settings will give you the 1 latest
version from all applicable version (0 <= timestamp <= 5).
Since it's pretty easy to set the times
Hi St.Ack:
Let say there are 5 versions for a column A with timestamp = [0, 1, 3, 6,
10].
I want to execute an efficient query that returns one version of the column
that has a timestamp that is equal to 5 or less. So in this case, it should
return the value of the column A with timestamp = 3.

Hi HBase guru:
I need some advises on a problem that I'm facing using HBase. How can I
efficiently query a version of a column when I don't know exactly the
version I'm looking for?
For instance, I want to query a column with timestamp that is less or equal
to N, if version = N is available, retur
