Example 1 with DeleteBuilder

use of co.cask.cdap.data2.util.hbase.DeleteBuilder in project cdap by caskdata.

the class HBaseMetricsTable method delete.

@Override
public void delete(byte[] row, byte[][] columns) {
    byte[] distributedKey = createDistributedRowKey(row);
    DeleteBuilder delete = tableUtil.buildDelete(distributedKey);
    for (byte[] column : columns) {
        delete.deleteColumns(columnFamily, column);
    }
    try {
        hTable.delete(delete.build());
    } catch (IOException e) {
        throw new DataSetException("Delete failed on table " + tableId, e);
    }
}

Example 2 with DeleteBuilder

use of co.cask.cdap.data2.util.hbase.DeleteBuilder in project cdap by caskdata.

the class HBaseTable method undo.

@Override
protected void undo(NavigableMap<byte[], NavigableMap<byte[], Update>> persisted) throws Exception {
    if (persisted.isEmpty()) {
        return;
    }
    // NOTE: we use Delete with the write pointer as the specific version to delete.
    List<Delete> deletes = Lists.newArrayList();
    for (Map.Entry<byte[], NavigableMap<byte[], Update>> row : persisted.entrySet()) {
        DeleteBuilder delete = tableUtil.buildDelete(row.getKey());
        delete.setAttribute(TX_MAX_LIFETIME_MILLIS_KEY, txMaxLifetimeMillis);
        for (Map.Entry<byte[], Update> column : row.getValue().entrySet()) {
            // we want support tx and non-tx modes
            if (tx != null) {
                delete.setAttribute(TxConstants.TX_ROLLBACK_ATTRIBUTE_KEY, new byte[0]);
                // TODO: hijacking timestamp... bad
                delete.deleteColumn(columnFamily, column.getKey(), tx.getWritePointer());
            } else {
                delete.deleteColumns(columnFamily, column.getKey());
            }
        }
        deletes.add(delete.build());
    }
    if (!deletes.isEmpty()) {
        hbaseDelete(deletes);
    }
