Thanks, Ryan. Is it possible to also get the latest versions before a parti=
cular timestamp on the shell , if I want to query older data ?=20
JG did provide me with the api call for the same - I need it for the shell =
as well.=20

Hey,

In the shell you can ask for more versions by saying:
get 'table', 'row', {COLUMN =3D> 'family', VERSIONS =3D> 4}

I believe you have to specify the COLUMN (as either 'family' or
'family:qualifier') if you want to specify VERSIONS.

As for versions via the API, there is only really 2 calls:
Scan.setMaxVersions(int)
Scan.setMaxVersions()

these set either the requested versions or the max the family can
store.  There is a similar call for Get.

PS: I just found 3 of your (unanswered) emails in my gmail spam
folder.  Sorry if it seems like no one is home - I know many of the
hbase devs use gmail, so it's possible your email address is confusing
things.
