Thanks to 梁景明 and Tatsuya Kawano. I use HBase 0.20.0, I did followwhat 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 followingmessage,

is my running way correct? or need something else be configured. Thanks
again.

Are you running zk on the node you are trying to run this code from? It
should not be saying localhost otherwise...

Also, set the zookeeper quorum instead of the hbase master and try again.

What you can also do is include in your classpath a directory whichcontains

the hbase-site.xml, hadoop-site.xml and zoo.cfg files. That ways you wont
need to set any config parameter in your code. The HBaseConfiguration will
automatically pick it up from the environment.

That's okay. You can check the mailing list archive if this happensagain:

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 whetherthere

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!
