Examples of RowMutations

org.apache.hadoop.hbase.client.RowMutations
Performs multiple mutations atomically on a single row. Currently {@link Put} and {@link Delete} are supported.The mutations are performed in the order in which they were added.
We compare and equate mutations based off their row so be careful putting RowMutations into Sets or using them as keys in Maps.

    checkRowValue(ROW_A, Bytes.toBytes(4L));
  }


  private void checkMutateRow() throws IOException {
    Put put = new Put(ROW_A).add(TEST_FAMILY, qualifierCol1, bytes1);
    RowMutations rowMutations = new RowMutations(ROW_A);
    rowMutations.add(put);
    hTableInterface.mutateRow(rowMutations);
    checkRowValue(ROW_A, bytes1);
