Examples of org.apache.hadoop.hbase.HTable.startUpdate()

org.apache.hadoop.hbase.HTable.startUpdate()
Start an atomic row insertion/update. No changes are committed until the call to commit() returns. A call to abort() will abandon any updates in progress. @param row Name of row to start update against. @return Row lockid.

    // Wait for the flush to happen
    LOG.info("Done. No flush should happen after this");


    // Do another round so to populate the mem cache
    for (int i = 0; i < NUM_ROWS; i++) {
      long id = table.startUpdate(new Text("row_" + String.format("%1$05d", i)));


      table.put(id, TEXT_COLUMN2, String.format("%1$05d", i).getBytes());
      table.commit(id);
