Shiraz,
I'm the one who started writing that page in September and I just kicked my
lazy ass to at least complete the example. Have a look!

Well, you could wrap InputStream with either BufferedInputStream
(and use BufferedInputStream.read(byte[] b, int off, int len))
or wrap InputStream with a DataInputStream (and use either
DataInputStream.read(byte[] b) or
DataInputStream.read(byte[] b, int off, int len))
In either case above, if
Rather than managing your own byte arrays, you could also just
have a stack local byte array of some size, read from
BufferedInputStream or DataInputStream into your stack local
array and write it into a ByteArrayOutputStream.
When you are done you can use ByteArrayOutputStream.toByteArray()
to
I took the old hbase 0.2.0 EC2 scripts and modified them to work with
Hadoop 0.18.2 / hbase 0.18.1. Things seemed to be working and I can see
the cluster with the different regions etc. of both the hadoop port
50030 and hbase 60010.
I will release these scripts once they are working properly.
Shiraz,
If you would like to read some more on what you can do with Hbase and
compare it to an RDBMS you may also find this article helpful:

I'm writing an HBase client application and I would like to be able to
configure all of the HBase configuration parameters without having to supply
the XML configuration files. I'm interfacing with HBase from within a JEE
application and I need to be able to access multiple HBase servers.
It looks like I answered my own question. I did some additional
investigation and it appears that the only parameter that needs to be
changed is hadoop.master.
That being said, are the HBaseConfiguration parameters documented anywhere?

Larry,
The HBaseConfiguration parameters are currently documented in
conf/hbase-default.xml of your hbase distro. Surely not the best solution.

10k columns is probably over what hbase is currently able to do (hbase-867).

What Andrew said and then, you might also look back in your logs to see if
you can find where the region 743469791 first gets exceptions.
Grep 743469791 in your master to find the unencoded name and use this
grepping the master to find which host it was last deployed to. Then go
there and grep
