Hi
I am trying to implement according to documentation and i also added this
line to connect remote server
HBaseConfiguration config = new HBaseConfiguration();
config.set(hbase.master, myserver.mycompany.com:6);
but I am getting following exception
WARNING: instantiating
Hi All
I have also try by enabling the web server on the remote machine and use the
following code.
String host=myserver.mycompany.com http://myserver.mycompany.com:6;
int port=80;
String protocol = http;
HBaseConfiguration config = new HBaseConfiguration();

You don't have to instantiate the webserver. It comes up on by
default. Browse to http://MASTER_HOST:60010/.
I'd suggest you read the 'getting started' doc referred to earlier.

getting back to your original question, we are using JMXBeans and Locater code
that return references to the proxies for the JMXBeans to allow remote clients
to access HBase without any knowledge of HBase or Hadoop

It seems my question is not clear:
does this call:
scan.setStartRow(Bytes.toBytes(lastDoc))
.. have any effect on rows returned for anyone else?
Thanks,

Make sure you are using a 64 bit JVM as opposed to 32-bit.. 32 bit java doesn't
allow more than 3-4 gigs..

Well, I have a 16G machine and I do not want to give all memory to hbase since
each hbase deamon will take 4Gigs - master and regionserver are running on the
same machines and also hdfs daemons.

Hi Avani,
4 gigs might be enough for your app.. But did you make sure that you are
using a 64-bit jvm?

I've found that the master doesn't need as much memory as the regionserver.
I've been successful giving the region servers 4GB or more and the master 1GB
or less.
(I used HBASE_MASTER_OPTS and HBASE_REGIONSERVER_OPTS in hbase-env.sh for
specifying different heap sizes)

Can you give me some more details or some reference links from where i can
learn how to use JMXBean stuff to connect to master server and then perform
operations on hbase.
Thanks

When you have a master that is confused like this, you can try this:
- make sure it isnt undergoing log splitting
- kill -9 the master
- restart the master
the startup code will check the cluster status then take appropriate action.
There is a new master which will make all this junk better
One thing you can do is to kill -9 the master process, then restart it
with bin/hbase-daemon.sh start master
This will clear the master state and it will inspect the cluster when
restarting to figure where things are.
If that doesn't work you can also restart HBase completely.

Hi Shuja-Ur-Rahman,
It would be nice if you would mention how you solved it in the mailing
list so that if someone else runs into the same problem they know how
to solve it.

Hey homies,
I'm trying to write some JavaScript (which I know little about) to
pull data out of HBase via Stargate via jQuery. To get around the
Single Origin Policy, I'm trying to do gets by using JSONP, which
embeds/retrieves requests in script tags. This seems to be a
relatively common way to
