about using HBase?

[ma qiang]

Dear colleagues;
         Now,I have to use HBase in my map and reduce functions, but I
don't know how to use. I have seen the examples in the FQA and
org.apache.hadoop.hbase. ,but I can't run it successfully. Can you
give me some simple examples make me manipulate HBase using java api
in my map and reduce functions as soon as possible.  Thank you very
much!

Please copy the hadoop-0.16.*-hbase.jar to ${hadoop_home}/lib folder.
And, Here's a exmple of hadoop-site.xml



   
      hbase.master
      a51066.nhncorp.com:60000
      The port for the hbase master web UI
      Set to -1 if you do not want the info server to run.
     
   
   
      hbase.master.info.port
      60010
      The port for the hbase master web UI
      Set to -1 if you do not want the info server to run.
     
   
   
      hbase.regionserver
      a51066.nhncorp.com:60020
      The port for the hbase regionserver web UI
      Set to -1 if you do not want the info server to run.
     
   
   
     hbase.regionserver.info.port
      61030
      The port for the hbase regionserver web UI
      Set to -1 if you do not want the info server to run.
     
   
   
      hbase.rootdir
      /tmp/hbase
      location of HBase instance in dfs
   



Thanks.

Thanks very much!
When I manipulate the HBase in map and reduce function,I need use the
java api about HBase. Can you tell me how to use it?

See the HBaseAdmin and HTable, HConnection classes.
If you use a eclipse for develop, i'd recommend the Outline Viewer.

Or, you can also use the HQL as describe below.

HQLClient hql = new HQLClient(new HBaseConfiguration(), MASTER_ADDRESS, null, null);
ReturnMsg rs = hql.executeQuery("create table webtable('content','title');");

Thank you very much!
I've used the HQL as you metioned,  but where is package including
HQLClient and ReturnMsg ?

It's a org.apache.hadoop.hbase.hql.

Or, Simply just use the 'ctrl + shift + o' key on eclipse tool. (simle)

Thanks.

Grandmotherly, If you want to retrieval the cell values, you should use the HTable.class because Result Set return policy doesn't implemented yet.

Thanks.

Thank you for your help!

You metioned hadoop-0.16.* , but I still use hadoop-0.15 ,I can't see
hadoop-0.16.* in the http://lucene.apache.org/hadoop/releases.html,
and I haven't found the org.apache.hadoop.hbase.hql . .So I'm not sure
I use the correct edition.

Ooops, then i'd recommend Hbase API instead of HQL.

http://lucene.apache.org/hadoop/docs/current/api/org/apache/hadoop/hbase/HBaseAdmin.html
http://lucene.apache.org/hadoop/docs/current/api/org/apache/hadoop/hbase/HTable.html

You can use these. For example :

HBaseAdmin admin = new HbaseAdmin(conf);
HTableDescriptor tableDesc = new HTableDescriptor("webtable");
tableDesc.addFamily(new HColumnDescriptor("anchor"));
tableDesc.addFamily(new HColumnDescriptor("content"));
admin.createTable(tableDesc);

B. Regards,

Dear ma qiang.

Firstly, please check the hbase status using hbase shell or hbase deamons log.
Also, If you didn't restart the hadoop, please re-start. (It means that configuration file doesn't loaded)

B. Regards,

Edward yoon @ NHN, corp.
