删除数据

功能简介

HBase通过Table实例的delete方法来Delete数据,可以是一行数据也可以是数据集。

代码样例

以下代码片段在com.huawei.bigdata.hbase.examples包的“HBaseSample”类的testDelete方法中

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.");
}
