Connect to hbase from remote machine - hadoop

Question

I have VM where habse is installed.
IP:192.168.20.10
I want to try to connect to hbase from my desktop:
Here is what I am trying>
public static void main(String[] args) throws IOException {
AbstractApplicationContext context = new ClassPathXmlApplicationContext("/META-INF/spring/hbase-beans.xml", HBaseConnection.class);
context.registerShutdownHook();
UserRepository userRepository = context.getBean(UserRepository.class);
List<User> users = userRepository.findAll();
System.out.println("Number of users = " + users.size());
System.out.println(users);
}
public List<User> findAll() {
return hbaseTemplate.find(tableName, "cfInfo", new RowMapper<User>() {
public User mapRow(Result result, int rowNum) throws Exception {
return new User(Bytes.toString(result.getValue(CF_INFO, qUser)),
Bytes.toString(result.getValue(CF_INFO, qEmail)),
Bytes.toString(result.getValue(CF_INFO, qPassword))
);
}
});
}
And this is my bean.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="hbaseTemplate" class="org.springframework.data.hadoop.hbase.HbaseTemplate">

</bean>
</beans>
This code works fine when I run directly in remote machine.When I am running same code from my windows machine by providing ip of hbase .,it doesnot return any value.

Answer 1

Configure your windows machine C:\Windows\System32\drivers\etc\hosts
file to resolve your HBase cluster node details. Recommended Make sure
DNS configuration is right!. i.e. addresses of all
nodes(Regionservers) of HBase Cluster is resolved from windows
machine.
