As I wasn't clear whether PageFilter was intended to be used in a Scan in
conjunction with other filters I did a little experimenting.
I took a guess - I couldn't find it documented, but maybe it is and I just
missed it - and combined my PageFilter with my other filters by creating a
FilterList
Apologies if this reply us not relevant, I'm posting just in case my approach
to this problem is useful.
I'm using 20.1 and I'm looking to solve this sane problem by applying the
filter to a scan on the root table and using the results to create
RowFilter instances which I use in a second scan.
Is the a way to just lock a family rather than an entire row? If not, has

Thank you Barney Frank, your detailed notes were very helpful in confirming I
was doing things correctly already on the client. I did a lot of tracing
through the HBase code and concluded that the problem lay with my server.
It looks like 0.20.0 has all sorts of DNS config entries and by defaul
All, sorry to bring this post back to life but I am still stuck :(
If anyone has some example 0.20.0 configurations and code they could share
with me regards to running a Java client on a different machine to HBase and
Hadoop that would be brilliant :)
Many thanks.

Thanks J-D,
Apologies for not including the HBase version details, you are correct I am
using 0.20.0. I made the recommended change so that my code now looks like

The Groovy & Grails high-ups seem to have already picked up on this, so it
should be fun to see where this leads.
Enjoy!

I have a family which contains an array, or list, of values. I don't mind
whether it is an array or a list or even an arraylist :)
At the moment I have gone down the quick and dirty route of serializing my
list into one column. While functionally this works sufficiently well to

Apologies for the long post but being an HBase newbie I'd like a sanity check
from wiser, more experienced folks with regards to my findings, and how I've
fixed the issue I think I've found, before going down the path of submitting
a formal patch.
To re-create the problem I was seeing in my app I

I think I'm looking at the same problem with HBase as Dingding Ye. I need to
be able to retrieve a list of rows sorted by data in a column and I'm not
sure how to go about it without resorting to performing the sort on the
client which feels like I'm just giving up.
My current thinking is to crea
That was the perfect test, I'm up and working nicely. Many thanks.

Thanks you for such a quick reply. I am afraid the link you sent me just took
me to the top of the HTable Javadoc page and so I am not clear which method
exactly you are referring to. Apologies if I have missed the point
somewhere.

The application I am building against HBase has a need for simple numeric
keys, the key for the first row inserted into a table should be 1, the
second row 2, etc.
I am working on HBase 0.20 RC1 using this excellent example as my template,
