Accessing Thrift Server to Write Data

Function Description

Input the host where the ThriftServer instance is located and the port that provides services, create a Thrift client, access the Thrift Server instance, and use the put and putMultiple commands to write data.

Example Code

• Invoking methods

  // Write data with put.
  putData(client, TABLE_NAME);
  
  // Write data with putlist.
   putDataList(client, TABLE_NAME);

• Using Put to write data

  The following code snippets are in the putData method in the ThriftSample class of the hbase-thrift-example\src\main\java\com\huawei\hadoop\hbase\examples packet.

  private void putData(THBaseService.Iface client, String tableName) throws TException {
       LOGGER.info("Test putData.");
       TPut put = new TPut();
       put.setRow("row1".getBytes());
  
       TColumnValue columnValue = new TColumnValue();
       columnValue.setFamily(COLUMN_FAMILY.getBytes());
       columnValue.setQualifier("q1".getBytes());
       columnValue.setValue("test value".getBytes());
       List<TColumnValue> columnValues = new ArrayList<>(1);
       columnValues.add(columnValue);
       put.setColumnValues(columnValues);
  
       ByteBuffer table = ByteBuffer.wrap(tableName.getBytes());
       client.put(table, put);
       LOGGER.info("Test putData done.");
   }

• Using putMultiple to write data

  The following code snippets are in the putDataList method in the ThriftSample class of the hbase-thrift-example\src\main\java\com\huawei\hadoop\hbase\examples packet.

  private void putDataList(THBaseService.Iface client, String tableName) throws TException {
       LOGGER.info("Test putDataList.");
       TPut put1 = new TPut();
       put1.setRow("row2".getBytes());
       List<TPut> putList = new ArrayList<>();
  
       TColumnValue q1Value = new TColumnValue(ByteBuffer.wrap(COLUMN_FAMILY.getBytes()),
           ByteBuffer.wrap("q1".getBytes()), ByteBuffer.wrap("test value".getBytes()));
       TColumnValue q2Value = new TColumnValue(ByteBuffer.wrap(COLUMN_FAMILY.getBytes()),
           ByteBuffer.wrap("q2".getBytes()), ByteBuffer.wrap("test q2 value".getBytes()));
       List<TColumnValue> columnValues = new ArrayList<>(2);
       columnValues.add(q1Value);
       columnValues.add(q2Value);
       put1.setColumnValues(columnValues);
       putList.add(put1);
  
       TPut put2 = new TPut();
       put2.setRow("row3".getBytes());
  
       TColumnValue columnValue = new TColumnValue();
       columnValue.setFamily(COLUMN_FAMILY.getBytes());
       columnValue.setQualifier("q1".getBytes());
       columnValue.setValue("test q1 value".getBytes());
       put2.setColumnValues(Collections.singletonList(columnValue));
       putList.add(put2);
  
       ByteBuffer table = ByteBuffer.wrap(tableName.getBytes());
       client.putMultiple(table, putList);
       LOGGER.info("Test putDataList done.");
   }
