java api error: connection to HMaster
My java code to create a Hbase table encounters errors, but the shell works well, through it I can create and read tables.
code:
HBaseConfiguration conf = new HBaseConfiguration();
HBaseAdmin admin = new HBaseAdmin(conf);
error information as follows

I am confused why it connect localhost:60000, may my hbase configuration be right? Would someone can help me solve this problem? Thanks!

Make sure you have the same jar that the server is running, as you can
see the error is about an RPC mismatch.

By default that's how it works, master listens on localhost on port 60000.

Hi Liu,
Did you try the stuff that Stack suggested in another thread? What was
the result? You'd better to try that, otherwise nobody will be able to
solve your problem. (We can't figure out the cause of the problem by
just looking at the client log you provided. We need more information
from you.) So please try that.
Also, can you tell us about your environment?
1. HBase version?
2. Distribution mode -- Standalone? Pseudo Distribution? Full Distribution?
3. Where are you trying to run your Java program? From the same
machine that HBase master is running on? or from a different machine?
4. What's in your configuration file (hbase-site.xml)?
5. So you can't run HBaseAdmin to create tables. How about regular
operations like inserting record to the database (HTable#put() )? Is
it working?
6. Why do you think it's wrong to connect to localhost:60000? Do you
think "localhost" part is wrong? or do you think "60000" part is
wrong?

Hi all,
The below code will explain to connect hbase server using hbase api. you
have to add library both hadoop-0.19.0 and hbase-0.19.3 in you classpath.
I have created small sample UI application using HBase. I have given source
also you can refer it.

RE: Sample application on HBase

I will update to hbase.0.20.x. as soon as possible.
This is my own interesting to develop applications using this platform. But,
I need support for this to further developing more.
No license for this..

This seems to be like a web based "enterprise manager" for hbase. I've
played with the "out of the box" web console for hbase 0.20 and this is
a nice compliment to actually play with columns and rows. This might be
something, or at least the inspiration for something, to add into a
