Hi i have installed ubuntu on my machine and installed hbase0.98-hadoop2. Then i edited hbase-env.sh file and hbase-site.xml. Now my hbase shell is working fine. But when i try to connect to hbase from Java code using hbase java api's. I get errors. My Code is:
Configuration hc = HBaseConfiguration.create();
HTableDescriptor ht = new HTableDescriptor("User");
ht.addFamily( new HColumnDescriptor("Id"));
ht.addFamily( new HColumnDescriptor("Name"));
System.out.println( "connecting" );
HBaseAdmin hba = new HBaseAdmin( hc );
System.out.println( "Master running ? "+ hba.isMasterRunning());
System.out.println( "Creating Table" );
hba.createTable( ht );
System.out.println("Done......");
My output is:
connecting

My Code is creating problem at HbaseAdmin. Any help please? Remember i installed standalone hbase and did not installed hadoop separately. It was the same package hbase0.98.6-hadoop2.

If you are using maven, please see if you are using the exact versioned dependencies as your hbase setup is. Foexample, if your hbase is suppose hbase-0.x.x you must add the dependency hbase-0.x.x in your project. Similarly check all other dependencies like hadoop, zookeeper as well. If not maven then download the proper jars and add them to your classpath. If you are unaware, go to the lib folder of your application and see the jars.
Hope this helps. Thanks
