问题
I am trying to run a HBase Java Client Program from Windows. All I have is 1) A Java Program without any compiler error 2) hbase-site.xml (No other HDFS or HBase config files I have. Only the above one.) When I run the program I get the following error-given in the last block. Do I miss something? Both I am giving here.
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.zookeeper.quorum</name>
<value>IP Address1,IPAddress2,IPAddress3</value>
</property>
</configuration>
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;
import java.io.IOException;
public class HConnect
{
public static void main(String[] args)
{
try
{
Configuration aConfig = HBaseConfiguration.create();
HTable aTable = new HTable(aConfig, "TestTable");
byte[] aRowKey = Bytes.toBytes("RowKey1");
Put aPut = new Put(aRowKey);
byte[] aColFamily = Bytes.toBytes("ColumnFamily1");
byte[] aColumn = Bytes.toBytes("Column1");
byte[] aColumnVal = Bytes.toBytes("ColumnValue1");
aPut.add(aColFamily, aColumn, aColumnVal);
aTable.put(aPut);
aTable.close();
}
catch(IOException aException_in)
{
System.out.println("");
}
}
}

回答1:
I did not have core-site.xml and later I had some connectivity issues to the HDFS name node. Once I solved these I am able to insert data.
Also I resolved the following dependencies while I developed the client program that inserts data into HBase: commons-lang-2.6 commons-logging-1.1.3 slf4j-1.7.5 protobuf-java-2.4.0a .
