Hi, I'm working with Michelan...
We are actually using the HBaseConfiguration object - which is why we
were confused when the client was trying to connect to zookeeper on
localhost. Even stranger was that all other functions work fine -
getting a table, putting and getting data. It is only the code that
adds indexing to the table that throws the error.
In the debug info we can see that...
1) when adding indexing to an existing table, it connects to
zookeeper, it disables the table, enables the table, creates the index
table and then tries to connect to zookeeper on localhost.
2) when adding a new table with indexing, it connects to zookeeper on
the server, creates the table and the index table and fails after that
trying to connect to zookeeper again, but again on localhost.
I have checked that we are using the same HBaseAdmin object the whole
time (which was constructed with the HBaseConfiguration object) and it
was only when we added the conf folder to the classpath as well that
it completed with no errors.
I don't have the code or the debug info with me right now, but
Michelan can send that to you in the morning - please let us know if
you need it?
Regards,
Seraph

Yes, you can also create a HBaseConfiguration object and configure it
with those exact configs (that you then provide to HTable).

Thank you. I have added the configuration folder to my client class
path and it worked.
Now I am faced with another issue, since this application will be
used in ColdFusion is there a way of making this work without
having the configuration as part of the class path?

Per
http://hadoop.apache.org/hbase/docs/r0.20.4/api/org/apache/hadoop/hbase/client/package-summary.html#overview
your client has to know where your zookeeper setup is. Since you want
to use HBase in a distributed fashion, that means you went through
http://hadoop.apache.org/hbase/docs/r0.20.4/api/overview-summary.html#fully-distrib
and this is where the required configs are.
It could be made more obvious tho.

This is the error that I get:

I'm working of a server and not standalone mode, where would I
change a setting that tells the "connectString" to point to the
server instead of "localhost".

Did you include the jar (contrib/indexed/hbase-0.20.3-indexed.jar)
in
your class path?

Hi.
I added the following properties to hbase-site.xml

<property>

I'm using hbase 0.20.3 and when I start hbase now it comes with
the following:

Caused by: java.lang.ClassNotFoundException:

Can you please help with this problem that I am having.
Thank you,
