问题
I am following this link to insert data into my hbase. I followed all the steps and written below code:
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.KeyValue;
import org.apache.hadoop.hbase.MasterNotRunningException;
import org.apache.hadoop.hbase.ZooKeeperConnectionException;
import org.apache.hadoop.hbase.client.Delete;
import org.apache.hadoop.hbase.client.Get;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;
public class Startclass {
private static Configuration conf = HBaseConfiguration.create();
public static void addRecord(String tableName, String rowKey,
String family, String qualifier, String value) throws Exception {
try {
HTable table = new HTable(conf, tableName);
Put put = new Put(Bytes.toBytes(rowKey));
put.add(Bytes.toBytes(family), Bytes.toBytes(qualifier), Bytes
.toBytes(value));
table.put(put);
System.out.println("insert recored " + rowKey + " to table "
+ tableName + " ok.");
} catch (IOException e){
e.printStackTrace();
}
}
public static void main(String[] agrs) {
try {
String tablename = "hl7";
Startclass.addRecord(tablename, "zkb", "pd", "dob", "10121993");
Startclass.addRecord(tablename, "zkb", "pd", "id", "007");
Startclass.addRecord(tablename, "zkb", "obr", "id", "007");
Startclass.addRecord(tablename, "zkb", "obr", "testname", "healthec");
Startclass.addRecord(tablename, "abc", "pd", "dob", "02051993");
Startclass.addRecord(tablename, "abc", "pd", "id", "011");
Startclass.addRecord(tablename, "abc", "obr", "id", "011");
Startclass.addRecord(tablename, "abc", "obr", "testname", "matrix");
} catch (Exception e) {
e.printStackTrace();
}
}
}
but i am getting below result

I have also created hbase table with proper column family name. I don't know what i am doing wrong. Please help.
回答1:
If you ran command create 'hl7','pd','obr' before running this code,there can be no way,it will not insert data in the table. Only such possibility is in case of incorrect configs passed or incompatible HBase(installation)-dependency(project).
