question Unable to Connect Hbase from Java client in Eclipse in Support Questions https://community.cloudera.com/t5/Support-Questions/Unable-to-Connect-Hbase-from-Java-client-in-Eclipse/m-p/277731#M207662 Hi  I am using cloudera quick start VM. my Hbase is working fine and using Hbase shell I am able to create table and do CRUD operations. I would like to connect Hbase with Java in Eclipse. I already created a Maven project in Eclipse and all the required Jar files downloaded properly. I written below code. package hbase; import java.io.IOException; import com.google.protobuf.ServiceException; import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.hbase.HBaseConfiguration; import org.apache.hadoop.hbase.MasterNotRunningException; import org.apache.hadoop.hbase.client.Connection; import org.apache.hadoop.hbase.client.HBaseAdmin; import org.apache.hadoop.hbase.client.ConnectionFactory; public class GetConnection { public static void main(String[] args) throws Exception { Configuration config = HBaseConfiguration.create(); //String path = this.getClass().getClassLoader().getResource("hbase-site.xml").getPath(); // config.addResource(new Path(path)); config.addResource("usr/lib/hbase/conf/hbase-site.xml"); config.set("hbase.zookeeper.quorum","localhost"); config.set("hbase.zookeeper.property.client.port","2181"); config.setInt("timeout", 120000); config.set("hbase.master", "localhost:60000"); Connection con = ConnectionFactory.createConnection(config); HBaseAdmin admin = new HBaseAdmin(config); try { HBaseAdmin.checkHBaseAvailable(config); } catch (MasterNotRunningException e) { System.out.println("HBase is not running." + e.getMessage()); return; } } } But Once I executed this code I am getting below error log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory). log4j:WARN Please initialize the log4j system properly. log4j:WARN See <A href="http://logging.apache.org/log4j/1.2/faq.html#noconfig" target="_blank" rel="noopener">http://logging.apache.org/log4j/1.2/faq.html#noconfig</A> for more info.
