How to run java program

[Liu Xianglong]

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!

I'm not exactly sure what you are doing, but it is not intended that you
would copy any code into the HBase Master.

You can run client programs standalone, they just need to have the
proper jars in their classpath (hadoop, hbase, zookeeper, log4j).

Hi, Tatsuya Kawano. What does "add path to Test.class to hbase-env.sh under
conf directory" mean?

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.

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.

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

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.

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 which contains
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.

Hi everyone,
This is a small application which I have developed that can be run on tomcat or JBoss.
It is quit easy.

This project is available in NetBeans Project format.

You can find it from this link..
 HBase small application 

In this URL you can find out IPH-HBase download link.

Get the project and load it in Netbeans as a web based project with libraries of hadoop-0.19.0 and hbase-0.19.3 versions in the class path.

MySQL library is also available inside of zip. This library helps to import data from MySQL to HTable.

Before running this application you have to set few parameters in the source code. That I have mentioned in the document.

Make sure that hadoop and Hbase server should be running before running the application.

This is sample application only. Do not take it for real time...

If any doubt is in this link, I expect your feedback of this.

It is absolutely free....

Thanks

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!
