Hi,
Have you taken a look at:

Hi dear,
I want to delete some rows with the specified column value, how to do it
more quickly?
Thanks.
Hi Lars,
What I am trying to do is to do a internal scan inside a coprocessor and
then stream the kv buffer as an byte array to a separate process for
processing. I hit a snag on how to reconstruct the kv in the separate
process from the byte array since I do not know what are the correct
offsets
To Ted,
--"Can you tell me why readings corresponding to different timestamps would
appear in the same row ?"
Is that mean the data versions which belong to the same row should at least
have the same timestamps?
For adding a row into HBase, I can use single Put instance, for example,
Put put = n

I don't think there's a CDH that includes Hadoop 1.2.1
So either your code is doing something slow or it's the reading itself. For
the latter, make sure you go through

this thread on the list were you can see some "live" perfo

Hi Jean,
HBase 0.94.6 and Hadoop 1.2.1 Cloudera Distributions..

Your details are missing important bits like you configurations,
Hadoop/HBase versions, etc.
Doing those random reads inside your MR job, especially if they are reading
cold data, will indeed make it slower. Just to get an idea, if you skip
doing the Gets, how fast does it became?

That means that the master cluster isn't able to see any region servers in
the slave cluster... is cluster b up? Can you create tables?

Hi,
I tried to configure a replication with 2 boxes (a&b). A hosts hbase &
zk and b only hbase. A is on zk:/hbase and b on zk:hbase_b. I used
start-hbase.sh script to start hbase and I changed
HBASE_MANAGES_ZK=false on both.
A is master and B is slave. I added a peer on A and when I list it
Hi Amit,
Would you be able to open a ticket summarizing your findings? Can you
provide a sample project that demonstrates the behavior you're seeing? We
could use that to provide a fix and, I hope, some kind of unit or
integration test.
Thanks,
Nick

Hi there,
Are you using the REST Gateway with JSON serialization? How are you forming
your queries? Do you use Jersey's "mapped" notation (with the '@' prepended
to attribute names)?
Please have a look at the recent comments [0] on HBASE-9435 and weigh in.
Thanks!
Nick

Not sure I follow.
You have a single row with two columns?
In your scenario you'd see that supplier c has 15k iff you query the latest
data, which seems to be what you want.
Note that you could also query as of TS 4 (c:20k), TS3 (d:20k), TS2 (d:10k)

I will say yes. 128mb is the max size, but only the real content is flushed
and that's what is displayed. This value is memstoreSize.get();

Hello,
In my understanding, the timestamp of each data version is generated by Put
command. The value of TS is either indicated by user or assigned by HBase
itself. If the TS is generated by HBase, it only records when (the time
point) that data version is generated (Have no meaning to the applica
