Thanks to 梁景明 and Tatsuya Kawano. I use HBase 0.20.0, I did follow what
梁景明 said, write my code as
HBaseConfiguration config = new HBaseConfiguration();
config.addResource("./conf/hbase-site.xml");
Then run it on my client PC. but it cann't work and get following message,
is my running way correct? or need something else be configured. Thanks
again.

That's okay. You can check the mailing list archive if this happens again:
http://www.nabble.com/HBase-User-f34655.html
So, I'm a bit late to reply, but you have found a way to get your
program working; that's great! As for "hbase-site.xml", please try
what 梁景明 said. (I'm forwarding the email just for sure.)
Also, are you running HBase 0.19? I would suggest to move to HBase
0.20.1, because there are lots of improvements in HBase 0.20. When you
use HBase 0.20.x, you no longer use "hbase.master", but
"hbase.zookeeper.quorum", so update your "hbase-site.xml". Take a look
at "hbase-default.xml", it has all the default properties including
"hbase.zookeeper.quorum".
Thanks,
Tatsuya

hi , at first u should add the configure files in hbase to ur
HBaseConfiguration
like this
conf.addResource("/hbase-site.xml");
and the file in ur hbase conf path.
if u change ur hbase conf ,just change it.
2009/10/27, Liu Xianglong <[email protected]>:
Now, I can run my program correctly if I add sentence
"config.set("hbase.master","<hmaster IP>:60000")", otherwise it will
report
the error I mentioned in last emails. So what do you think about the
problem? Should I change some configuration? Now I do not add
"hbase.master"
in hbase-site for full-distributed mode.

Subject: How to run java program
Hi, everyone. I am using HBase Java API to retrieve data in HTable.
Now
I
run my java program in HMaster node, but I am wondering whether there
are
other ways to run java program, or need I copy my java program into
server
every time I want to run them?
Thanks!
Best Wishes!
