We're going to do a push to github later today, along with other
patches that require more testing.

hi there ! i wonder if there is a reliable tutorial how to compile hbase in
eclipse.
i would be grateful if abyone could help me.
thanks in advance
Sorry for that :)
I still didn't push to github the new version as I'm still testing a
few unrelated improvements that are coming in (nothing fancy, as it's
already in apache's SVN).

After running stargate with no issues for a month or two, I encountered some
problems today, and can't quite figure it out. Perhaps someone could give me
advice.
I start up stargate

Ok. I applied patch to internal git. 10 hours of mr job and still looks fine.

I cant find any documentation which says you shouldn't write to the same HBase
table you're scanning. But it doesnt seem to work... I have a mapper
(subclass of TableMapper) which scans a table, and for each row encountered
during the scan, it updates a column of the row, writing it back to
Are at least export file format compatible?

Sorry, no migration as in there's nothing special to do... it just
works. And like Ryan said, no coming back.

Thank you, Ryan, Jean-Daniel.
That's extremely nice. I don't care about going back so much.
One question though -- in the case of going back -- are export routine
formats compatible or i'd have to pump the data thru a format of my own if i
want to re-flush it back?
Thanks.

On Thu,
HTML directory listing is not Stargate output. Got something else running on
port 8080?

What jvm version are you using? A readwrite lock should not be able to

RWLock can indeed deadlock with itself - it doesn't support lock
upgrade from read to write.

Sorry - that was the lastest release in the downloads section of
hbase.apache.org. I'll upgrade right away.
We're on 1.6.0_17. I've seen warnings about u18 having problems. Do you
recommend u20?

Actually, I first encountered the problem when I was using HBase standalone,
i.e. outside of map-reduce. I use an HTable client to simultaneously scan and
update a table. While iterating the scan, I do a put() of a single column back
to the current row returned by the scanner.
What I see is
Yes that should work. What version of hbase are you using? I would
appreciate a test case :-)

Can you also try 0.20.6 and see if you can repro on that? There has
been a lot of changes between those versions that potentially affect
this issue.

Right now, most of our boxes have 3 disk in them. We take a small
partition on each of those and raid stripe them together to use as the
OS partition then allocate the rest of the disks as JBOD for HDFS storage.
We are building out a new cluster and I'm wondering if there are any
better
Sorry to jump in on the tail end of this...
What sort of buffer size do you have on your client?
What it sounds like is that you're doing a put() but you don't see the row in
the table until either the client side buffer is full or if you've flushed the
buffer which then writes the records to
I didnt try changing the write buffer size from the default. Looks like the
default is 2MB. I'll try setting it to zero. Thanks for the tip.
