Deleting Data
Function Description
HBase allows you to delete data (a row of data or data sets) using the delete method of a Table instance.
Sample Code
The following code snippets are in the testDelete method in the HBaseExample class of the com.huawei.bigdata.hbase.examples packet.
public void testDelete() { LOG.info("Entering testDelete."); byte[] rowKey = Bytes.toBytes("012005000201"); Table table = null; try { // Instantiate an HTable object. table = conn.getTable(tableName); // Instantiate a Delete object. Delete delete = new Delete(rowKey); // Submit a delete request. table.delete(delete); LOG.info("Delete table successfully."); } catch (IOException e) { LOG.error("Delete table failed ", e); } finally { if (table != null) { try { // Close the HTable object. table.close(); } catch (IOException e) { LOG.error("Close table failed ", e); } } } LOG.info("Exiting testDelete."); }
